Embodiment Construction

[0015] Implementation 1.

[0016] Petroleum resin (a large amount), paraffin wax (a small amount), and pigments (a small amount) are about 45% in total

[0017] Methyl octadecanoate (a large amount), methyl palmitate (a small amount), 2,6-di-tert-butyl p-cresol (a small amount) total about 45%

[0018] About 9% of toluene and xylene

[0019] Phosphor 1%

[0020] This batch of temperature-changing ink is 1 kg, and the ink with temperature-changing and fluorescence detection functions can be obtained by fully grinding according to the above formula ratio.

[0021] Implementation 2.

[0022] Petroleum resin (a large amount), paraffin wax (a small amount), and pigments (a small amount) are about 48% in total

[0023] Methyl octadecanoate (a large amount), methyl palmitate (a small amount), 2,6-di-tert-butyl p-cresol (a small amount) total about 41%

[0024] About 11% of toluene and xylene

[0025] This batch of temperature-changing ink is 2 kg, and the ink with temperature-c...

Abstract

The invention discloses temperature sensitive ink, which is suitable for offset printing or flexography on a rotary press. The temperature sensitive ink consists of following three parts by weight percent: totally about 48 percent of petroleum resin (large amount), paraffin (small amount) and pigment (trace amount), totally about 41 percent of methyl stearate (large amount), methyl palmitate (small amount) and 2, 6-ditertiary butyl-p-hydroxytoluene (trace amount), and totally about 11 percent of methylbenzene and dimethylbenzene. If necessary, about 3 percent of fluorescent powder can be added. By adopting the special formula, the ink is suitable for offset printing or flexography on the rotary press on which common temperature sensitive ink cannot be used. Moreover, the ink has the temperature sensitive color changing function or not only the temperature sensitive color changing function but also the fluorescence detection function.

Description

[0001] A temperature-changing ink. Suitable for offset or flexo printing on a web press. technical field [0002] The temperature-changing ink of the invention belongs to the field of chemical industry. Background technique [0003] Common temperature-changing inks currently on the market have the following deficiencies: [0004] 1. Not suitable for offset printing or flexographic printing on rotary presses. That is, it is not suitable for printing on various invoices, securities, tickets and the like. [0005] 2. The same area uses a large amount of ink under the same printing conditions, resulting in high costs. [0006] 3. Low technical content, single detection method, easy to imitate. Contents of the invention [0007] In order to overcome the shortcomings of ordinary temperature-changing inks currently on the market, the present invention uses a new ink formula to provide a new formula of temperature-changing inks. This ink has high technical content and is not e...
