Abstract
The following polyalkoxysiloxane compounds (A) and (B): PA1 (A): polyalkoxysiloxane compounds represented by the rational formula SiO.sub.x (OR.sup.1).sub.y (OR.sup.2).sub.z, wherein z/(y+z)=0.05 to 0.5 by mole, 0.5.ltoreq.x.ltoreq.1.5, 2x+y+z=4, R.sup.1 is a methyl group and/or an ethyl group, and R.sup.2 is an organic group different from R.sup.1 ; PA1 (B): polyalkoxysiloxane compounds represented by the rational formula SiO.sub.x (OR.sup.1).sub.y (OR.sup.2).sub.z, wherein 0.5.ltoreq.x.ltoreq.1.5, 2x+y+z=4, R.sup.1 is a methyl group and/or an ethyl group, and R.sup.2 is at least one of the alkyl groups having 3 to 4 carbon atoms; are provided. These polyalkoxysiloxane compounds can be used advantageously for the coat-forming compositions or aqueous emulsion-forming compositions.
