Abstract

PURPOSE:To provide anti-fogging performance by using an highly hygroscopic org. material for paint for printing inside surfaces of glass. CONSTITUTION:An inorg. coloring agent is mixed with a base material prepd. by adding a polmn. initiator of an azo compound such as azobisisobutyronitrile, peroxide such as benzoyl peroxide or persulfate such as ammonium persulfate to hydroxyalkyl acrylate or hydroxyalkyl methacrylate and polymerizing these and the mixture is coated 2 on the inside surface of glass 1.
