  • Publication number: 20210116812
    Abstract: The present invention provides a positive photosensitive resin composition having high light transmittance, high heat resistance, and excellent pattern processability. The present invention provides a positive photosensitive resin composition containing polysiloxane (A), a naphthoquinonediazide compound (B), and a solvent (C); in which the polysiloxane (A) has at least one structure selected from the following general formulae (1) to (3), and has at least one structure selected from the following general formulae (4) to (6); in which, in the general formulae (1) to (3), R4 represents a C2-C6 hydrocarbon group having an unsaturated double bond; R1 represents a single bond or a C1-C4 alkylene group; R2 in the general formula (2) represents a hydrogen atom or a C1-C4 alkyl group; and R3 in the general formula (3) represents an organic group; in which R2 in general formula (5) represents a hydrogen atom or a C1-C4 alkyl group; and R3 in the general formula (6) represents an organic group.

  • Patent number: 10431753
    Abstract: The present invention is a substrate for a display, the substrate having a film B including a polysiloxane resin on at least one surface of a film A including a polyimide resin, wherein the film B contains inorganic oxide particles therein, and the present invention has an object to provide a substrate for a display: being able to be applied to a color filter, an organic EL element, or the like without the need to carry out any complex operations; allowing high-definition displays to be manufactured; and being provided with a low CTE, a low birefringence, and flexibility.

  • Publication number: 20190101828
    Abstract: A resin composition including a polysiloxane (A) and a solvent (B), wherein the polysiloxane (A) contains at least one partial structure represented by any of the general formulae (1) to (3), and the relationship between the film thickness X and the film thickness Y, which respectively represent the thickness of a film produced by application of the resin composition and subsequent drying at 100° C. for 3 minutes and the thickness of the film after subsequent heating at 230° C. for 5 minutes, satisfies the following inequation: (X?Y)/x?0.05. The resin composition exhibits excellent coating properties on rugged surface and has excellent planarization properties even if the resin composition is in a form of thin film. (R1 represents a single bond or a C1-4 alkyl group; R2 represents a C1-4 alkyl group; and R3 represents an organic group.

  • Patent number: 10209554
    Abstract: The present invention discloses a method for producing a laminated-resin black matrix that has a sufficient optical density and a low reflectance and that can be precisely processed, and a color filter substrate that includes a laminated-resin black matrix substrate produced by the method. The method for producing a laminated-resin black matrix substrate includes the step of exposing, in a single step, a laminate of a coating A of a non-photosensitive resin composition A that contains a light-shielding material and a coating B of a resin composition B that contains a light-shielding material, the laminate being on a substrate, and the step of developing the exposed laminate. The color filter substrate includes red, green, or blue pixels formed in apertures in a laminated-resin black matrix substrate produced by the method.
