Abstract

The invention provides a temperature-changing ink, which comprises, by weight, 30-60 parts of an aqueous acrylic resin, 15-40 parts of a petroleum resin, 1-2 parts of calcium carbonate, 5-10 parts ofa temperature-changing pigment, 3-6 parts of a dispersant, 3-8 parts of an antifoaming agent, and 2-5 parts of an anti-settling agent. According to the present invention, the temperature-changing inkhas good temperature change effect, wherein the temperature change reaction is a reversible reaction; and with the temperature-changing ink, the printed product has bright color, and does not easily fade.

Description

technical field [0001] The invention belongs to the technical field of ink, in particular to a temperature-changing ink. Background technique [0002] Common temperature-changing inks currently on the market have the following deficiencies: they are not suitable for offset printing or flexographic printing on rotary machines. That is, it is not suitable for printing on various invoices, securities, tickets, etc.; the same area uses a large amount of ink under the same printing conditions, resulting in high costs; low technical components, single detection method, easy to imitate. Contents of the invention [0003] The present invention proposes a temperature-changing ink, which solves the defects of the above-mentioned temperature-changing ink in the prior art. [0004] Technical scheme of the present invention is realized like this: [0005] A temperature-changing ink, which consists of the following parts by weight: 30-60 parts of water-based acrylic resin, 15-40 parts...
