20150361035 | URETHANE (METH) ACRYLATE COMPOUND - The present invention provides a thermosetting resin which enables the production of a carbon fiber reinforced plastic having a good workability and excellent mechanical properties by hand lay up (HUP) molding, resin transfer molding (RTM) or vacuum assisted resin transfer molding (VaRTM). The urethane (meth) acrylate compound (A) according to the present invention is an urethane (meth) acrylate produced by reacting a compound having two or more isocyanate groups with a monoalcohol compound containing ethylenically unsaturated groups or by reacting a compound having two or more isocyanate groups with a monoalcohol compound containing ethylenically unsaturated groups and an alcohol compound having two or more hydroxyl groups, said urethane (meth) acrylate compound (A) being characterized by having an isocyanate group and ethylenically unsaturated groups. | 12-17-2015 |
20150138778 | CRYSTALLINE UNSATURATED POLYESTER RESIN COMPOSITION FOR LED REFLECTOR, GRANULAR MATERIAL COMPRISING SAID COMPOSITION, LED REFLECTOR PRODUCED BY MOLDING SAID GRANULAR MATERIAL, SURFACE-MOUNT-TYPE LIGHT-EMITTING DEVICE, AND LIGHTING DEVICE AND IMAGE DISPLAY DEVICE EACH EQUIPPED WITH SAID LIGHT-EMITTING DEVICE - The purpose of the present invention is to provide a crystalline unsaturated polyester resin composition which has improved fluidability upon being mixed with an inorganic filler, a white pigment or the like. | 05-21-2015 |
20130071785 | ALCOHOL COMPOUND, A POLYESTER RESIN, AN UNSATURATED POLYESTER RESIN, A RESIN PARTICLE AND AN ELECTROPHOTOGRAPHIC TONER - It is an object of the present invention to provide a new alcohol compound, a polyester resin, an unsaturated polyester resin, a resin particle and an electrophotographic toner using the compound capable of using the renewable resources as a part of a raw material. | 03-21-2013 |
20110123922 | POLYESTER RESIN FOR TONER AND TONER FOR DEVELOPING AN ELECTROSTATIC CHARGE - A toner for developing an electrostatic charge image which contains a polyester resin as a binder resin is provided. The toner has excellent toner properties including low temperature fixing properties, anti-blocking property and anti-offset property, etc. Also a polyester resin for a toner is provided, which is used in the above-mentioned toner. As the binder resin for toner, a polyester resin comprising (1) an aromatic dicarboxylic acid and (2) a disproportionated rosin as an acid component, and (3) a tri- or more-valent polyhydric alcohol as an alcohol component is used, wherein the molar ratio (3)/(1) of the alcohol component (3) and the acid component (1) is from 1.05 to 1.65 and the molar ratio (2)/(1) of the acid components (2) and (1) is from 0.40 to 2.60. | 05-26-2011 |
