The present invention aims to provide an interlayer film for a laminated glass which is easily peelable without autohesion even after storage in a stacked state, and a laminated glass prepared using the interlayer film for a laminated glass. The present invention relates to an interlayer film for a laminated glass, having a large number of protrusions on at least one surface, the surface having an arrangement density of the protrusions of 3 protrusions/mm.sup.2 or more, and the protrusions having an area ratio of 15 to 75% to the surface.

An article includes a glass substrate and an insert within the glass substrate, the surface roughness (Ra) of the glass substrate and the insert is about 0.05 m to about 0.2 m.

A method for finishing an edge of a glass laminate structure comprising the steps of assembling a glass laminate structure having a first glass sheet, a second glass sheet and an interlayer material intermediate the first and second glass sheets and placing a compressive material on a first edge of the assembled structure. A vacuum can be applied to a second edge of the assembled structure and the assembled structure heated to a predetermined temperature at or above a softening temperature of the interlayer material. The vacuum and temperature can be maintained for a predetermined period of time whereby the compressive material provides an in situ finish for the first edge of the glass laminate structure.
