Abstract
Abstract A polysiloxane composition comprising (i) an alkoxysilyl group-containing polysiloxane containing at least six siloxane structures having the following formula (I) in a moleculewherein R1 represents a methyl group, ethyl group or phenyl group, and R2 represents a group selected from the group consisting of hydrocarbon group and ether bond-containing hydrocarbon groups having 1 to 6 carbon atoms; and(ii) an alcohol having the formulawherein R4 represents a C1-C18 alkyl group, a phenyl group or a benzyl group, R5 represents C1-C6 alkylene group and p is an integer of 0-20.
