FIELD: chemistry.
SUBSTANCE: present invention relates to an intermediate layer for laminated glass. The intermediate layer for laminated glass consists of a lustreless and sound-insulating composition of a polyvinyl acetal polymer. Said composition contains powder of finely dispersed inorganic particles and a plasticiser in amount of 45 pts. wt or more per 100 pts. wt of the polyvinyl acetal polymer. The composition also contains finely dispersed infrared radiation screening particles.
EFFECT: improved sound insulation properties of the intermediate film.
