Problems solved by technology

[0004] In order to meet the application in this field, the terminal market uses the existing sublimation transfer paper suitable for textile printing and hard materials for printing processing. Due to the difference between the sublimation transfer paper and the printing process, the printing accuracy on the hard material is also different. Uneven, even broken lines, white spots, white spots, misalignment, batch color difference and blurred border problems often occur, and the qualified rate of finished products is low
In the current technology, such as the technical solution disclosed in CN201410726797.3 "An Easy-to-Use Inkjet Sublimation Transfer Paper", the invention patent inkjet sublimation transfer paper includes an ink support layer, a paper fiber bonding layer, a base Paper layer and back coating, in which the paper fiber bonding layer acts as a water-repellent agent, but this technical solution still cannot effectively prevent ink seepage and low ink transfer rate

Abstract

The invention relates to a sublimation transfer paper suitable for hard materials and a preparation method thereof. The transfer paper comprises a base paper layer, a pre-coat layer on the front side of the base paper, an ink-absorbing layer and an anti-curling layer on the back side of the base paper. Through the improvement of coating formula and process, the product has high transfer rate, high saturated ink absorption capacity, and no ink halo phenomenon at the junction of colors, which solves the problem of sublimation transfer paper due to the matching of ink vaporization rate and different carriers in the transfer process. There are various problems such as white spots, broken lines, color difference, white spots, misalignment, etc.

Description

technical field [0001] The invention relates to the field of thermal sublimation transfer paper, in particular to a thermal sublimation transfer paper suitable for hard materials and a preparation method thereof. Background technique [0002] At present, most products of sublimation transfer paper are used with textile fabrics. Textile fabrics are mainly made of chemical fiber materials, which are divided into two categories: woven fabrics and knitted fabrics. The paper is tightly bonded together for ink sublimation transfer. Even if there is a little wrinkle in the textile, the vaporized sublimation transfer ink can fill the gap well, so that there will be no color difference and white spots. The mainstream technology of digital printing. [0003] With the advancement of thermal sublimation transfer technology, thermal sublimation transfer paper has begun to be used in the field of hard materials, including hard materials such as copper plates, aluminum plates, wood plates...
