摘要:
A method of preparing a resin composition for hard coat, comprises: a first step of obtaining a polyfunctional (meth)acrylate monomer modifying agent by addition reaction between a modifying agent having a thiol group and a three- or more functional (meth)acrylate monomer to form a covalent bond between the thiol group and acryloyl group and/or methacryloyl group, and a second step of modifying metal oxide microparticles with the polyfunctional (meth)acrylate monomer modifying agent that is obtained from the first step.

A thermally color-developing reversibly thermochromic pigment which shows a uniform color density in the coloring temperature range and also shows an optimal ΔH value within a range of from 3 to 40° C. Thermally color-developing reversibly thermochromic pigments of a three component system having a ΔH value within a range of from 7 to 40° C. in which at least essential three components including (a) an electron-donating chromic organic compound, (b) a specified compound selected from the gallic acid esters and (c) a reaction medium selected from alcohols, esters, ketones and hydrocarbons; which reversibly generates color reactions of both of the compounds within a specified temperature range and has a melting point of less than 50° C., are microencapsulated, and of a four component system having a ΔH value within a range of from 3 to 25° C. in which a compound (d) selected from monomer compounds having a melting point of 50° C. or more or polymer compounds having a softening point of 70° C. or more is added to the three component system.

A reversibly thermochromic light-shielding/light-transmitting laminate member. More particularly, the invention relates to a reversibly thermochromic light-shielding/light-transmitting laminate member which changes not only in color but in transmittance with temperature.
摘要:
A reversible thermochromic display article which comprises a substrate and, formed thereon, a heat coloration image containing a heat coloration type reversible thermochromic composition which is colored by heating and is decolored by cooling and a heat decoloration image containing a heat decoloration type reversible thermochromic composition which is decolored by heating and is colored by cooling, or having a multilayer structure comprising a heat coloration layer containing the heat coloration type reversible thermochromic composition and a heat decoloration layer containing the heat decoloration type reversible thermochromic composition, wherein the heat coloration type reversible thermochromic composition is a microcapsule composition which contains, enclosed therein, (a) an electron-donating chromatic organic compound, (b)′ an electron-accepting compound selected from gallic acid esters, and (c) a reaction medium having a melting point lower than 50° C. which is selected from alcohols, esters, ketones, and hydrocarbons and which causes color reactions between the two components to occur reversibly at specific temperatures.
