Title: Ink jet recording sheet
Inventor: TSUCHIDA TETSUO
IPC: C09D139/04
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To improve recording density, recording quality, and water resistance and light-fastness of recorded images by adding water-soluble cation polymer containing at least one kind of monomer unit expressed by specific formulas in a recording sheet. SOLUTION: A water soluble cationic polymer containing at least one kind of polymer unit expressed by formulas I, II is added in an ink jet recording sheet. In the formulas, R1 shows a hydrogen atom or a methyl group. As such, a hydrophilic property is enhanced, thereby achieving a prompt admixture with water ink. Furthermore, an existence in the vicinity of anionic dye can be accomplished by the static interaction of cationic property. Also, the matter in the formula I functions effectively as a light stabilizer, and the matter in the formula II functions as a UV ray absorbent, thus restraining dye decomposition. In this structure, light-fastness, a survival rate of images, a quality of pictures, and water resistance can be improved.

Abstract: PURPOSE:To enable the manufacturing time to be shortened by a planar current blocking layer on a substrate, and etching the current blocking layer to form a current constriction groove and active layer film thickness control grooves, thereby reguiring only one etching process. CONSTITUTION:On a substrate 1 made of GaAs and shaped in a flat board, the crystal growth of GaAs is performed to form a current blocking layer 2. Then, a photoresist is applied on the layer 2, which is exposed to light and developed to form a resist layer 5. Then, when the layer 2 is etched, in the central part of the layer 2, the etching proceeds to the upper area of the substrate 1, and in the end parts of the layer 2, the etching proceeds only to the intermediate area. Accordingly, a current constriction layer 3 reaching the substrate 1 from the layer 2 is formed in the central part, while in the end parts, active layer film thickness control grooves 4 are formed which do not reach the substrate 1. With this, only one time of etching is required, whereby the manufacturing time is shortened.
