Document Type and Number:
WIPO Patent Application WO/2020/244455
Kind Code:
A1
Abstract:
The present invention relates to a skin layer composition for forming a uniformly light-transmitting PVC artificial leather. The skin layer composition comprises a PVC resin, a skin layer plasticizer, a stabilizer, and a pigment paste. The skin layer composition contains 0.51-5.6% of the pigment paste based on the total weight of the skin layer composition, and the pigment paste is an inorganic-organic composite pigment paste formed by mixing an inorganic toner, an organic toner, and a pigment paste plasticizer. The present invention also relates to a PVC artificial leather capable of uniformly transmitting light. The PVC artificial leather comprises a PVC skin layer formed from the aforementioned skin layer composition. The PVC artificial leather according to the present invention can be applied to artificial leather, such as in car interiors, that has a color which is expected to have sufficient hiding power but have uniform transmission of light under illumination, and has a more uniform light transmission effect than traditional materials.
