INK OR COATING MATERIAL FOR POLYACETAL RESIN MOLDING, METHOD FOR PRINTING OR COATING SURFACE OF POLYACETAL RESIN MOLDING, AND PRINTED OR COATED ITEM

摘要

PURPOSE: To obtain an ink or coating material which is excellent in adhesion to a polyacetal resin and useful for decorating the surface of a polyacetal resin molding by selecting an ink or coating material contg. a specific resin. CONSTITUTION: An ink or coating material is selected which contains an aliph. polyether resin wherein 75-93mol% of all the repeating oxyalkylene units are repeating oxymethylene units (e.g., a copolymer formed from 35mol% 1,3- dioxolane, 55mol% trioxane, and 10mol% glycidyl methacrylate) pref. in an amt. of the resin of 1-40wt.% of the ink or coating material. After being activated, the surface of a polyacetal resin molding is printed or coated with the ink or coating material.
