摘要:
An object of the present invention is to provide: a polyvinyl acetal resin for a heat-developable photosensitive material capable of preventing skinning in the coating process of the photosensitive layer of the heat-developable photosensitive material, preventing deterioration of image characteristics and coloration of the coating solution, and suppressing the occurrence of odor at the time of producing the heat-developable photosensitive material and heat development. The present invention provides a polyvinyl acetal resin for a heat-developable photosensitive material used for a photosensitive layer of the heat-developable photosensitive material, which has a residual acetyl group content of 25 mol % or less, residual hydroxyl group content of 17-35 mol %, polymerization degree of 200 to 3,000, which is obtained by an acetalization of a polyvinyl alcohol mixture containing polyvinyl alcohol resins having different polymerization degrees, the content of the polyvinyl alcohol having a polymerization degree of 600 or less being 50 wt % or higher in the polyvinyl alcohol mixture.

The present invention relates to optical power-limiting devices, and more particularly, to an optical power-limiting passive (self-adaptive) device and to a method for limiting solar power transmission in devices such as windows, using scattering level changes in a novel thermotropic composition that contains salt nano or microparticles embedded in a solid transparent host layer, where temperature change induces change in the refraction index of the matrix as well as of the embedded particles, creating a scattering layer, substantially reflecting the incident light thus limiting the amount of light passing through the window, green house covers, car sun roofs, solar panel windows and protection layers on housing roofs and walls, as a function of ambient temperature.

The present invention provides a carbon-coated vanadium dioxide particle which can suppress interparticle sintering during high-temperature firing, has high crystallinity and high oxidation resistance, and can maintain excellent thermochromic properties even after long-term storage or use. The present invention also aims to provide a resin composition, a coating film, a film, an interlayer film for laminated glass, a laminated glass, and a film to be attached each obtained using the carbon-coated vanadium dioxide particle. The present invention relates to a carbon-coated vanadium dioxide particle, including a vanadium dioxide particle and a coating layer containing amorphous carbon on a surface of the vanadium dioxide particle. The amorphous carbon is derived from carbon contained in an oxazine resin and has a peak intensity ratio of a G band to a D band of 1.5 or greater as determined from a Raman spectrum. The coating layer has an average thickness of 50 nm or less. The coating layer has a coefficient of variation (CV value) of thickness of 7% or less.
