Abstract

The invention discloses thermochromic paint for printing. The thermochromic paint is prepared from resin, pigment, solvent and an auxiliary; by weight, the resin includes 5+ / -1% of polyurethane, 15+ / -2% of thermoplastic acrylic resin and 31+ / -1% of special petroleum resin, the pigment includes 25+ / -5% of thermochromic pigment, and the solvent includes 5+ / -0.5%, 6+ / -0.5% of 783 and 9+ / -0.5% of ethylene glycol monobutyl ether.

Description

technical field [0001] The invention relates to a coating for printing, in particular to a thermochromic coating for printing. The paint involved in the present invention can be widely used for surface printing of paper materials such as books, newspapers, and packaging materials, and can produce signs and warnings of product surface coating color changes caused by product temperature changes. Background technique [0002] Color-changing materials refer to substances that change color as the external environmental conditions change. Color-changing materials are widely used, such as thermosensitive recording materials for instruments, temperature display materials, self-display photographic materials, etc. There are also many applications of color-changing materials in high-tech fields, such as optical information storage, nonlinear optical materials, and military camouflage, which play an increasingly important role. In recent years, in order to meet the modern people's pu...
