Example Embodiment

[0008] Specific embodiment 1: In this embodiment, the material of the ink-absorbing layer of the photographic paper consists of 0.5-10 parts by weight of polyhedral oligomeric silsesquioxane, 25-75 parts of ethylene-vinyl acetate copolymer emulsion, and 50-75 parts of deionization Water composition.

[0009] The preparation method of the ink-absorbing layer material of the photographic paper in this embodiment is as follows: the polyhedral oligomeric silsesquioxane is added to 50% under the condition that the stirring speed is 500-800r / min and the adding speed is 0.05-1 part by weight / min. Stir in ~75 parts by weight of deionized water for 10-20 minutes, then add 25-75 parts by weight of ethylene-vinyl acetate copolymer emulsion, and stir for 30-40 minutes to obtain the ink-absorbing layer material of photographic paper.

[0010] The ethylene-vinyl acetate copolymer emulsion used in this embodiment is produced by Nanjing Yonghong Chemical Co., Ltd.; the polyhedral oligomeric silse...

Example Embodiment

[0011] Specific embodiment two: this embodiment is different from specific embodiment one in that the material of the ink-absorbing layer of the photographic paper consists of 1 to 9.5 parts by weight of polyhedral oligomeric silsesquioxane and 28 to 73 parts of ethylene-vinyl acetate copolymer emulsion It is composed of 53-73 parts deionized water. Others are the same as the first embodiment.

[0012] The ink-absorbing layer material of the photographic paper obtained in this embodiment is used as a coating to print ribbons and pictures with a MUTOH RJ8000 inkjet printer. After observation, the ink-jetted ribbons and pictures have high color saturation, high gloss, and good definition. , There is no halo phenomenon.

Example Embodiment

[0013] Specific embodiment three: this embodiment is different from specific embodiment one in that the material of the ink-absorbing layer of the photographic paper consists of 1.5-9 parts by weight of polyhedral oligomeric silsesquioxane and 30-70 parts of ethylene-vinyl acetate copolymer emulsion. It is composed of 55-70 parts deionized water. Others are the same as the first embodiment.

[0014] The ink-absorbing layer material of the photographic paper obtained in this embodiment is used as a coating to print ribbons and pictures with a MUTOH RJ8000 inkjet printer. After observation, the ink-jetted ribbons and pictures have high color saturation, high gloss, and good definition. , There is no halo phenomenon.

Abstract

The invention provides a photographic paper ink absorbing layer material, and relates to a material for a photographic paper coating. The material solves the problem that the prior photographic paper ink absorbing layer material easily generates ink diffusion phenomenon on the surface of an ink absorbing layer. The material consists of 0.5 to 10 portions of polyhedral oligomeric silsesquioxane, 25 to 75 portions of ethylene-vinylacetate copolymer latex and 50 to 75 portions of deionized water. The photographic paper ink absorbing layer material obtained by the invention can be used as a photographic paper inkjet ribbon and a picture of the ink absorbing layer; through observation, the ribbon and the picture subjected to spraying and printing have high color saturation and lustrousness, good definition and no ink diffusion phenomenon; and after the material is subjected to heat preservation for one hour in an oven of 200 DEG C, heat preservation for seven days in an oven of 70 DEG C, or insolation for half a year under the sun, the saturation, the lustrousness and the definition of the ribbon and the picture subjected to spraying and printing are unchanged, and no ink diffusion phenomenon generates. By testing of a scanning electron microscope SEM, grains of the photographic paper ink absorbing layer material have uniform granular diameter, favorable dispersion and no aggregation phenomenon.

Description

technical field [0001] The present invention relates to a material for the coating of photographic paper. Background technique [0002] Cast Coating Photo Paper is the Cast Coating Photo Paper. Its coating is made of micron-sized silica. After special processing, the brightness and whiteness can reach the level of traditional photo paper. Although it has a waterproof coating, the base paper is the same base paper as swelling photo paper, so the overall waterproof performance is poor, and after printing a high-saturation picture, the coating surface is prone to ink smudges. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ink-absorbing layer material for photographic paper in order to solve the problem that the ink-absorbing layer material of the existing photographic paper is prone to blurring on the surface of the ink-absorbing layer. [0004] The ink-absorbing layer material of the photo paper of the present...
