Abstract: A curable resin composition is provided which uses a fumarate copolymer which is excellent in thermal discoloration resistance as a binder component and is capable of forming details of a color filter. The curable resin composition of the present invention is a photocurable resin composition for forming a protective layer, RGB pixels, a black matrix or a spacer of a color filter, and contains as a binder component a fumarate copolymer having at least a molecular structure wherein a constituent unit represented by the following Formula 1 and a constituent unit having an acidic functional group(s) are linked, preferably further having a constituent unit with an ethylenically unsaturated bond: wherein, each of R1 and R2 is independently a branched C3-8 alkyl group which may be substituted, or a C4-8 cycloalkyl group which may be substituted.

Abstract: A curable resin composition containing as the binder a fumarate copolymer which is excellent in thermal discoloration resistance and capable of forming details of a color filter, namely, a photocurable resin composition useful in forming overcoats, RGB pixels, black matrixes or spacers in the production of color filters, which contains as the binder a fumarate copolymer having a molecular structure comprising constituent units represented by the general formula (1) and constituent units having acidic functional groups, and preferably further containing constituent units having ethylenically unsaturated bonds: (1) wherein R1 and R2 are each independently branched C3-8 alkyl which may be substituted, or C4-8 cycloalkyl which may be substituted.

Abstract: There is provided an antenna whose outside shape can be miniaturized while maintaining a gain at a desired level with respect to a radio wave of a wide frequency range. The antenna is configured by using a core of a laminate structure. The core is a plate of a rectangular outside shape, configured to have a laminate structure including each of first, second and third resin layers. The first resin layer has magnetic powder mixed therein and formed as a middle layer, and the second resin layer and the third resin layer made of resin only without magnetic powder mixed therein are formed to sandwich the first resin layer therebetween. In the core of the laminate structure, it is preferable to use a polymer resin for each of the resin layers, and to use soft ferrite powder as the magnetic powder.

Abstract: A resin composition suitable for manufacturing an electrical insulative resin film for a printed wiring board is composed of 80 to 99.5 mass % of a first graft copolymer (a) and 0.5 to 20 mass % of a second graft copolymer (b). In the first graft copolymer (a), 15 to 40 parts by mass of an aromatic vinyl monomer are grafted to 60 to 85 parts by mass of a random or block copolymer composed of monomer units selected from nonpolar ?-olefin monomers and nonpolar conjugated diene monomers. In the second graft copolymer (b), 5 to 30 parts by mass of an aromatic vinyl monomer are grafted to 70 to 95 parts by mass of a random or block copolymer composed of 60 to 90 mass % of a monomer unit, which is selected from nonpolar ?-olefin monomers and nonpolar conjugated diene monomers, and 10 to 40 mass % of an aromatic vinyl monomer unit.

Abstract: A novel polydialkylsiloxane/polyamide copolymer which is excellent in biocompatibility, mechanical strength, and heat moldability, applicable for use in medical materials, ophthalmic materials, cosmetics, and electronic materials, and has a main chain represented by the formula (4), one end represented by the formula (5) and another end represented by the formula (6): —(NH—A—NHCO—B—CO)m—  (4) —NH—A—NH—X2  (5) —X1  (6) wherein the ratio of —R1—(Si(R2) (R3)—O)n1-Si(R2) (R3)—R1— as A to the divalent organic group having 1 to 20 carbon atoms as A is within the range of 1:0.01˜100, and the proportion of X1 and X2 being hydrogen atoms is 10% or less relative to all the end groups, a process for producing the same, and a variety of its uses.
