Abstract
Abstract An ink composition for indicating progress and completion of vulcanization of rubber articles comprising, per 100 parts by weight of the composition, (i) 0.01 to 10 parts by weight of at least one methine dye, (ii) 1 to 40 parts by weight of at least one member selected from the group consisting of rosin, rosin derivative, petroleum resin, phenol resin, xylene resin, alkyd resin, cumarone-indene resin, acrylic resin, epoxy resin, ketone resin and styrene-maleic acid resin, (iii) 0.5 to 50 parts by weight of at least one high molecular weight component selected from the group consisting of cellulose resin, polyvinyl butyral, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer, polyamide, synthetic rubber and natural rubber, (iv) 30 to 80 parts by weight of at least one organic solvent capable of dissolving the components (ii) and (iii), and (v) 0.1 to 50 parts by weight of at least one halogenated organic acid.
