Abstract: An adhesive containing a ladder-type polysilsesquioxane which firmly bonds metals and synthetic resins and an adhesive sheet having an adhesive layer formed by using the adhesive on at least one side of a substrate are provided. An adhesive comprises a ladder-type polysilsesquioxane having a recurring unit of the following formula (I) in the molecule, wherein R1 represents a polymerizable functional group, and R2 represents the same group as R1, an alkyl group having 1 to 6 carbon atoms which may have a substituent, an alkoxy group having 1 to 6 carbon atoms which may have a substituent, or a phenyl group which may have a substituent, and the adhesive sheet has an adhesive layer formed by using the adhesive on at least one side of the substrate.

Abstract: The present invention provides a process for producing a polysilsesquioxane graft polymer (1) which includes applying ionizing radiation or heat to a mixture including a polysilsesquioxane compound (2) and a vinyl compound (3), a polysilsesquioxane compound including an iniferter group, and a pressure-sensitive adhesive and a pressure-sensitive adhesive sheet using the polymer. According to the present invention, a process for producing a polysilsesquioxane graft polymer which may be used as a pressure-sensitive adhesive exhibiting excellent heat resistance and cohesive force, and the like are provided. In the formula, A represents a linking group, R1 represents a hydrocarbon group which may have a substituent, R2 represents a hydrogen atom or the like, R3 represents a polar group or the like, R4 represents a hydrogen atom or the like, k1 to k3 represent arbitrary positive integers, 1 to n represent zero or an arbitrary positive integer (excluding the case where “m=n=0”), and Q represents an iniferter group.

Abstract: There are disclosed a silicate-containing sheet which comprises a silicate of one metal or at least two composite metals, which metal and metals are selected from the group consisting of the groups 4 to 13 series 4-metals of the periodic table, the groups 4 to 15 series 5-metals of the periodic table, and the lanthanoids series metals, and are preferably selected from the group consisting of Ti, Fe, Co, Ni, Cu, Zn, Ga, Zr, Ag, In, Sn, Sb and Ce; and further a label comprising the above silicate-containing sheet. The silicate-containing sheet mentioned above can afford a functional sheet which has catalytic actions such as ultraviolet rays-attenuating properties, antimicrobial properties and antifouling properties at a low manufacturing cost.
