Abstract

The invention relates to ink bearing paper for thermal dye sublimation record, which comprises a base material, wherein a back coating is coated on one surface of the base material, the other surface of the base material is sequentially coated with an intermediate layer and an ink bearing layer from inside to outside, and the intermediate layer comprises the raw materials in parts by weight: 100 parts of polyurethane resin, 10-50 parts of EVA (Ethylene-Vinyl Acetate) resin, 0.1-10 parts of hardening agent, 1-60 parts of inorganic pigment and 700-900 parts of solvent. According to the ink bearing paper, the intermediate layer using the polyurethane resin and the EVA resin as main binding agents is additionally arranged between the base material and the ink bearing layer, thus the elasticity and adhering property of the ink bearing paper and the light fastness of a printed image during printing are improved.

Description

technical field [0001] The invention belongs to the technical field of ink printing paper, and in particular relates to an ink printing paper for dye sublimation thermal transfer recording and a preparation method thereof. Background technique [0002] In the past, photographs were developed by using silver halide photo technology to send the photographic film to the printing shop for manual development. With the rapid expansion of the current digital camera market, the digital photo printing industry is also growing rapidly. Digital photo printing is to selectively print the photos you want from the image memory card. As long as there is a small digital photo printer, photos can be printed anytime and anywhere without being limited by space. This conversion of photo printing methods has drawn attention to the photo printing technology for printing digital photos. The digital color printing technology based on photos includes inkjet method, electronic photo method, therma...
