PURPOSE:To prepare a compsn. which exhibits excellent printing characteristics and a distinct color change optimum sterilizing conditions by mixing a specific coating dispersion, poly(meth)acrylic acid, a superfine particulate filler, and a polar solvent. CONSTITUTION:The objecting compsn. is prepd. by mixing a coating dispersion contg. a compd. of the formula: A-N=N-B (wherein A is a heterocyclic compd. residue selected from the group consisting of pyridine, quinoline, isoquinoline and triazole rings each contg. a nitrogen atom not directly attached to an alkyl group; and B is a coupling component) (e.g. C.I. Disperse Red 58), poly(meth) acrylic acid or an acrylic acid-methacrylic acid copolymer, a superfine particulate filler selected from the group consisting of silica, aluminum oxide, and titanium oxide, and a polar solvent (e.g. isopropyl alcohol). |
