TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Material: The base material is glass or electroconductive base material. The electroconductive base material has conductive layer (5) laminated on the surface of base material main material (4). The conductive layer contains indium tin oxide or fluorine-doped tin oxide.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Properties: The remaining coal quantum in the porous titanium oxide layer when the titanium oxide containing paste is heat processed at 400 degrees C for 1 hour in air, is less than 1000 ppm when porous titanium oxide powder is formed. The crystal form of the titanium oxide particles is anatase type. Preferred Composition: The content of the titanium oxide particles is 3-100 %mass with respect to 100 %mass of titanium oxide containing paste. The paste further contains dispersing agent. The laminated material is formed using transparent base material which transmits 85% or more of visible light.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compound: The crosslinking agent is chosen from formulae: (Rv1)-(CH(CH3)CH2O)n-(CH2CH(CH3)O)m-(Rv2) (I) or (Rv3)-((CH2)4O)p-(Rv4) (II).Rv1=group having polymerizable unsaturated group, preferably group of formula: (H2C=C(R11)-C(=O)-O)-;Rv2=group having polymerizable unsaturated group, preferably group of formula: -(C(=O)-C(-R12)=CH2);Rv3=group having polymerizable unsaturated group, preferably group of formula: (H2C=C(R21)-C(=O)-O)-;Rv4=group having polymerizable unsaturated group, preferably group of formula: -(C(=O)-C(-R22)=CH2);R11,R12,R21,R22=H or methyl;andm+n,p=1-20.The monomer has (meth)acryloyl group.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The thermally vanishing resin particles have oxypropylene unit or oxytetramethylene unit, and are obtained by reacting crosslinking agent having polymerizable unsaturated group and monomer having polymerizable unsaturated group. 99 %Mass or more of the resin particles decompose when the resin particles are heat-processed at 400 degrees C in air for 1 hour. The particle size change rate of the resin particles after swelling with terpineol, is 20% or less. The crosslinking agent and monomer are reacted in the mass ratio of 1:99-75:25.
