Abstract:
PROBLEM TO BE SOLVED: To provide a titanium dioxide-free coating system which has both good shielding characteristics and a combination of surface characteristics, for example, low gloss, soft touch feeling, anti-polishing property, easy cleaning function, dirt pickup resistance, solvent resistance or the like. SOLUTION: The multilayer coating system comprises at least two layers including a layer of base coating which provides good shielding function for substrates and a second layer of clear top coating which provides surface protection functions for the coating system. The base coating composition comprises an opaque (co)polymer having at least one void per (co)polymer particle. The top coating composition comprises a duller (co)polymer chosen from a multi-stage (co)polymer, a single stage crosslinked (co)polymer, and mixtures thereof. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an adhesive layer for an optical film applicable to an optical film, and formed of an aqueous dispersion type adhesive, which has high durability capable of suppressing foaming or peeling even under a high temperature and high humidity environment. SOLUTION: The adhesive layer for an optical film is formed by applying the aqueous dispersion type adhesive, comprising an aqueous dispersion liquid, in which at least a base polymer is dispersed in water, and drying the liquid, characterized in that the amount of residual monomer in the adhesive layer is 5-100 ppm to 1g solid content in the adhesive layer.

Abstract:
PURPOSE: A base coat and clear coat coating is provided to improve staining resistance and to have controllable gloss. CONSTITUTION: A base coat and clear coat coating comprises a substrate comprises a substrate; a first coating having a higher pigment volume concentration than a critical pigment volume concentration arranged on the substrate; a second transparent matt coating which is arranged on the first coating and includes 1-99 weight% of a granular polymer with a particle diameter of 0.5-30 micron based on the weight of the second coating. The second coating additionally comprises 1-99 weight% of a film-forming emulsion polymer or polyurethane dispersion based on the total weight of the second coating.
