THERMOPLASTIC POLYMER FILM COATING COMPOSITION, METHOD FOR PREPARING THERMOPLASTIC POLYMER FILM COATING COMPOSITION, MODIFIED THERMOPLASTIC POLYMER FILM, AND METHOD FOR PREPARING MODIFIED THERMOPLASTIC POLYMER FILM

摘要

Provided are: a thermoplastic polymer film coating composition which has only minimal deterioration of drop-flowing properties caused by friction during film formation or spreading, exhibits excellent drop-flowing properties from the start of spreading, maintains excellent drop-flowing properties over a long period of time even after spreading, and furthermore, has an extremely non-sticky film surface coated with a drop-flowing agent; a method for preparing a modified thermoplastic polymer film using such a composition; and a modified thermoplastic polymer film obtained by such a preparation method. This thermoplastic polymer film coating composition is a compound in which a polyether-modified silicone, a specific polyoxyalkylene derivative, and a polyalkyleneglycol having a number-average molecular weight of 1500-50000 are contained at a specific ratio in a specific modified inorganic cation colloidal sol obtained by hydrolyzing a specific inorganic cation colloidal sol with a specific silanol-forming organic silane compound.
