Embodiment 1

[0023] Polyamide-modified alkyd resin, prepared by the following method:

[0024] Alcohol-hydrocarbon co-soluble polyamide versamid940 is prepared by reacting with alkyd resin at 190°C for 60 minutes. Its weight percentage is: alcohol-hydrocarbon co-soluble polyamide 20%, alkyd resin 80%;

[0025] Offset printing ink formula: (weight percent)

[0026]

[0027] The various components are mixed, stirred, rolled and dispersed to obtain the product.

[0028] The ink is proofed on neutral paper with IGT, and after drying, use 3M company scotch600 ink adhesion standard test tape to test the binding fastness. The results are as follows: no falling off.

Embodiment 2

[0030] Polyamide-modified alkyd resin, prepared by the following method:

[0031] Alcohol-hydrocarbon co-soluble polyamide P1074 is prepared by reacting with alkyd resin at 200°C for 50 minutes. Its weight percentage is: alcohol-hydrocarbon co-soluble polyamide 10%, alkyd resin 90%;

[0032] Offset printing ink formula: (weight percent)

[0033]

[0034] The various components are mixed, stirred, rolled and dispersed to obtain the product.

[0035] The ink is proofed on neutral paper with IGT, and after drying, use 3M company scotch600 ink adhesion standard test tape to test the binding fastness. The results are as follows: no falling off.

Embodiment 3

[0037] Polyamide-modified alkyd resin, prepared by the following method:

[0038] Alcohol-hydrocarbon co-soluble polyamide versamid950 is prepared by reacting with alkyd resin at 210°C for 30 minutes. The percentage by weight is: 5% of alcohol-hydrocarbon co-soluble polyamide and 95% of alkyd resin.

[0039] Offset printing ink formula: (weight percent)

[0040]

[0041] The various components are mixed, stirred, rolled and dispersed to obtain the product.

[0042] The ink is proofed on neutral paper with IGT, and after drying, use 3M company scotch600 ink adhesion standard test tape to test the binding fastness. The results are as follows: no falling off.

Abstract

The invention discloses an offset ink for improving polyester film binding fastness, which comprises the following components by weight: 5-25% of polyamide-modified alkyd resin, 40-70% of rosin modified phenolic resin, 5-25% of organic pigments, and 1-10% of additives. The offset ink of the invention has a simple preparation flow, and has good binding fastness with paper substrates.

Description

technical field [0001] The invention relates to an offset printing ink, in particular to an offset printing ink printed on a polyester film. Background technique [0002] In the printing industry, offset printing inks are widely used. The bonding fastness of offset printing inks is good on ordinary paper substrates, but on some special film substrates, especially polyester films with low surface energy, the bonding fastness of offset printing inks is not good. Ideal, especially when printing on some paper and film composite substrates (such as paper containing polyester anti-counterfeiting threads or anti-counterfeiting films), offset printing inks are required to meet both the bonding fastness on paper and the film on the film. Bond fastness. Therefore, on the basis of general offset printing inks, it is of great significance to develop inks with high binding fastness to polyester films.
