Embodiment 1

[0025] A kind of color inkless printing paper, comprises base material layer, inkless coating and protective layer, described protective layer comprises fluorocarbon resin, adhesion promoter, solvent and auxiliary agent, and the thickness of described protective layer is 20 μ m, so The fluorocarbon resin is selected from polytetrafluoroethylene resin, accounting for 25% by mass, and the adhesion promoter is selected from tetraethyl titanate, accounting for 2% by mass, and the solvent is water, accounting for 2% by mass. is 68%, and the auxiliary agent is selected from dibutyl phthalate, accounting for 5% by mass; the ink-free coating is coated on the substrate layer, including three heat-sensitive layers, from the top The heat-sensitive cyan layer, the heat-sensitive red layer and the heat-sensitive yellow layer are all 25 μm in thickness; the heat-sensitive cyan layer is a cyan triarylmethane dye layer; the heat-sensitive red layer is A red triarylmethane dye layer; the therm...

Embodiment 2

[0027] A kind of color inkless printing paper, comprises substrate layer, precoat, inkless coating and protective layer, and the thickness of described protective layer is 10 μ m, comprises fluorocarbon resin, adhesion promoter, solvent and auxiliary agent, so The fluorocarbon resin is selected from polyvinylidene fluoride resin, accounting for 30% by mass, and the adhesion promoter is selected from n-butyl titanate, accounting for 1% by mass, and the solvent is water, accounting for 1% by mass. The percentage is 67%, and the auxiliary agent is selected from dimethyl phthalate, and the mass percentage is 2%; the ink-free coating is coated on the substrate layer, including three heat-sensitive layers, from From top to bottom, there are heat-sensitive cyan layer (3), heat-sensitive red layer (4) and heat-sensitive yellow layer (5); the heat-sensitive cyan layer (3) is selected from cyan spiropyran dyes layer; the heat-sensitive red layer (4) is selected from the red spiropyran d...

Embodiment 3

[0032]The invention provides a kind of color inkless printing paper, comprising substrate layer, pre-coating layer, inkless coating layer and protective layer, and described inkless coating layer is coated on the described substrate layer, comprises three thermosensitive Layers, from top to bottom are heat-sensitive cyan layer (3), heat-sensitive red layer (4) and heat-sensitive yellow layer (5); heat-sensitive cyan layer (3), heat-sensitive red layer ( 4) and the heat-sensitive yellow layer (5) are provided with an intermediate spacer layer between the two layers, which is a mixture of resin and filler, and its function is mainly to control the discoloration temperature of each layer more accurately. The heat-sensitive cyan layer (3) is selected from the cyan furanone dye layer; the heat-sensitive red layer (4) is selected from the red furanone dye layer; the heat-sensitive yellow layer (5) is selected from Yellow furanone dye layer. The protective layer includes fluorocarbo...

Abstract

The invention relates to colored inkless printing paper which comprises a base material layer, an inkless coating and a protective layer, and the protective layer comprises fluorocarbon resin, an adhesion promoter, a solvent and an auxiliary agent, the fluorocarbon resin is selected from one or more of polytetrafluoroethylene resin, polyvinylidene fluoride resin, polytrifluorochloroethylene resin, vinyl ether resin and polyvinyl fluoride resin and accounts for 5-30% by mass, the adhesion promoter is selected from one or more of tetraethyl titanate and tetrabutyl titanate and accounts for 0-2% by mass, and the solvent accounts for 1-5% by mass. The solvent is water and accounts for 60-85% by mass, and the auxiliary agent is selected from one or more of dibutyl phthalate, dimethyl phthalate, polyethylene wax and dimethyl silicone oil and accounts for 2-5% by mass. Based on the colored inkless printing paper, colored advertisement images and texts can be directly printed on a PET material through inkless printing.

Description

technical field [0001] The invention relates to the technical field of printing consumables, in particular to a color inkless printing paper. Background technique [0002] The types of printers are basically divided into dot matrix printers, inkjet printers and laser printers. They all need matching printing materials when printing: matching ribbons for dot matrix printers, matching inks for inkjet printers or integrated ink cartridges, and matching inks for laser printers. Toner or toner cartridges, so the printing materials need to be replaced regularly, and the used waste ribbons, ink cartridges or toner cartridges are not easy to recycle, causing great pollution to the environment. [0003] In order to completely eliminate the pollution of waste printing materials to the environment, retire ink cartridges, do not use ribbons and toner cartridges, but only rely on a special paper, that is, ink-free printing paper, which can output exquisite pictures or text through the en...
