PROBLEM TO BE SOLVED: To provide a composition for interlayer membrane that is suitable for obtaining the interlayer membrane that can hold the adhesion between the interlayer membrane and the glass within proper range in both cases, at the beginning and after passage of time, the interlayer membrane for laminated glass that is produced by using the same and laminated glass produced by using the interlayer membrane. SOLUTION: This composition for interlayer membrane comprises 100 pts.wt. of poly(vinyl butyral) and 20-60 pts.wt. of oligoethylene glycol di-(2-ethyl- hexanoate) and is prepared by dissoliving 8 pts.wt. of the poly(vinyl butyral) to 100 pts.wt. of triethylene glycol 2-ethylhexanoate and has the cloud point of 90-130 deg.C. The interlayer membrane for laminated glass is prepared by forming the composition to a membrane. The laminated glass is prepared by intervening the interlayer membrane between at least two sheets of glass and integrating them.
