Abstract

The invention discloses an anti-curling image recording material and a preparation method thereof. The image recording material comprises a support body and an image recording layer arranged on one side of the support body, the image recording layer is obtained by drying a coating liquid, and based on the total mass of the coating liquid, the coating liquid comprises inorganic particles with the content of 8-33 wt%, and a solvent with the content of 10-30 wt%, a water-based adhesive, wherein the content of the water-based adhesive is 1.5-7.5 wt%; the content of the silane coupling agent is 1 to 5 weight percent; a cross-linking agent, wherein the content of the cross-linking agent is 0.01 to 0.1 wt%; an organic solvent, wherein the content of the organic solvent is 6-20 wt%; and deionized water, wherein the content of the deionized water is 54.49 wt%-83.49 wt%. Therefore, the shrinkage internal stress, generated in the drying process, of the coating can be obviously reduced, and the hidden danger of curling in the drying process is effectively eliminated; in addition, the coating process of the curling control layer can be omitted, the curling resistance of the image recording material is improved, the production cost can be remarkably reduced, and large-scale production of the image recording material is facilitated.

Description

technical field [0001] The present invention relates to the field of imaging, in particular, to a curl-resistant image recording material and a preparation method thereof. Background technique [0002] With the continuous improvement of living standards, video recording has become an indispensable part of people's lives. Video recording faithfully records important moments in life, and each photo records and condenses beautiful moments into eternity. The production of photos is to fix and display the images through specific technical processing methods on the image recording materials to form photos. [0003] The image recording material includes a traditional silver salt photosensitive recording material, that is, a photosensitive layer is coated on a support, and after exposure, a photograph is made by processing such as developing and fixing. With the advancement of technology, image recording materials also include inkjet recording materials, that is, coating an ink-abs...
