Patent ID: 8450405

Claim:
A method for making an exposed-edge design type side glass or an exposed-edge design type front glass of an automobile, which comprises: forming an interlayer film by laminating a plurality of films each comprising a poly(vinyl acetal) resin and at least one plasticizer selected from the group consisting of triethylene glycol di-2-ethylhexanoate, tetraethylene glycol di-2-ethylhexanoate, triethylene glycol di-n-heptanoate, and tetraethylene glycol di-n-heptanoate; wherein said interlayer film shows a temperature dependence of loss tangent in which the lowest-temperature side maximum of loss tangent appears at 30° C. or lower when examining said laminate of films for dynamic viscelasticity measured by the shear method; interposing said interlayer film between at least a pair of glass panels; laminating the interlayer film with said at least a pair of glass panels to form an integral sheet; and forming said exposed-edge design type side glass or said exposed-edge design type front glass of an automobile from said integral sheet.
