PROBLEM TO BE SOLVED: To provide intermediate layer films that have heat-shielding properties, without having to disperse nanoscale semiconductor particles in the volume of a plasticizer-containing intermediate layer sheet.SOLUTION: A heat-shielding laminated glass laminate comprises at least one sheet A containing a polyvinyl acetal PA and optionally at least one plasticizer WA, and at least one sheet B containing a polyvinyl acetal PB and at least one plasticizer WB, positioned between two glass sheets. Prior to lamination of each, a proportion of the plasticizer WA of less than 16 mass% is dispersed in the sheet A, a proportion of the plasticizer WB of at least 16 mass% is dispersed in the sheet B, and heat-shielding particles are dispersed in the sheet A. |
