PARTIALLY TRANSPARENT PAPER
Document Type and Number:
Japanese Patent JPH038898
Kind Code:
A
Abstract:
PURPOSE: To obtain the title paper capable of clearly, simply forming transparent parts such as marks and/or characters on a base paper by impregnating a base paper with an ionizing radiation-curable resin followed by ionizing irradiation to cure the resin.
CONSTITUTION: At least part of a base paper (e.g. one of a variety of base papers 20-300g/m2 in areal weight) is impregnated with an ionizing radiation- curable resin [e.g. polyalkylene glycol poly(meth)acrylate] followed by ionizing irradiation (pref. using electron beams or ultraviolet rays) to cure the resin, thus obtaining the objective transparent paper. In case ultraviolet rays are to be used, it is preferable that said resin is incorporated with a photo-initiator such as benzoin.
