DESCRIPTION
COLOR AND PATTERN PRINTING TECHNIQUE APPLIED BETWEEN COATING LAYERS FORMING ARTIFICIAL LEATHER
FIELD OF INVENTION
This invention is related to a process and a product manufactured through such process that is firstly used in this sector in the world integrating coating and pattern rotation and paper transfer printing and being different from the artificial leather used in furniture, shoemaking, garment and accessories sectors. The printing technique applied between the coating layers forming the artificial leather in the method developed by this invention ensures the manufacturing of the product with a natural leather appearance, higher color friction and color light fastness by means of an printing technique.
PRIOR ART
In the prior art, patterned artificial leather is manufactured by transferring different colors and patterns on the surface of the artificial leather by means of pattern cylinders or paper transfer printing technique. It is difficult to obtain both high color friction fastness and unavoidable to have changes in the original appearance and permanence of the paper pattern in the productions according to the known technique.
MANUFACTURING OF ARTIFICIAL LEEATHER COATED WITH POLYU REETH AN - POLYVYNYLCHLORIDE
In the known technique of artificial leather production, carrier paper (patterned) in the coating machine is provided with the requested thickness and weight and dried by being coated by polyurethane and/or polyvinyl chloride, solvent and other auxiliary chemicals by the first blade. The chemical carrier paper being dried reaches at the second blade and its chemical is transferred to the carrier paper similarly by means of coating polyurethane and/or polyvinyl chloride, solvent and other auxiliary chemicals at requested thickness and weight. Similar to the former application, the chemical carrier paper being dried reaches at the third blade and its chemical is transferred to the carrier paper similarly by means of
coating PU and/or PVC, solvent and other auxiliary chemicals at requested thickness and weight. Finally, bottom surface is glued onto paper with chemical, and dried. The product is obtained by the separation of the carrier paper from its bottom surface in its outlet from the machine.
PRINTING PROCESS ACCORDING TO THE PRIOR ART
Artificial leather processed in coating machine reaches at the printing machine, and here desired pattern is applied on the surface of the artificial leather. The printing solution consisting of dye, solvent and other auxiliary chemicals is applied on the surface of artificial leather by patterned rotation printing method, then dried and wrapped. Additionally, the colored pattern on paper is transferred on artificial leather by using pattern paper in the paper transfer machine. However, color abrasion fastness and light fastness of colored printing applied on the surface of artificial leather is very low in comparison to the data of the process developed by this invention.
OBJECTIVES FOR THE DEVELOPMENT OF INVENTION
In developing the process relating to the colored and patterned printing technique applied between coating layers forming the artificial leather developed by this invention; it is aimed to produce artificial leather having both genuine leather appearance and high color friction and light fastness with rich color / pattern appearance.

DESCRIPTION OF INVENTION
The process relating to the colored and patterned printing technique applied between coating layers forming artificial leather developed by this invention and patterned flexo printing, printed printing and transfer paper printing on the product manufactured according to the said process are realized in two phases. In this process, pattern-printing by flexo printing, printing or transfer paper printing system is not applied on the surface of artificial leather.
Phase 1 - Artificial leather is manufactured by applying pattern flexo printing, printing (emprime) or transfer paper printing on the back surface of one or more layers forming the surface of artificial leather and then giving other layers continuously or discontinuously.
Phase 2 - Following the application of pattern flexo printing, printing (emprime) or transfer paper printing on surface of semi-finished artificial leather having been coated or on the surface of coagulated surface to be coated, artificial leather is manufactured by carrying out transparent (without dye) or transparent with dye coating process. Thus, rich
color/pattern appearance is achieved with high color, friction and light fastness without changing the original look of the carrier paper.
Alternative processes where the product developed by this invention has natural leather appearance and rich color / pattern appearance with high color friction and light fastness are comprised as follows:
The alternative processes of the Phase 1 are mentioned below:
