TECHNICAL FIELD

The present invention relates to a laminated glass.

BACKGROUND ART

A laminated glass having an intermediate film of e.g. a resin provided between a pair of glass plates is excellent in safety, since fragments do not scatter upon breakage, and thus, it is widely used in e.g. windowpanes of vehicles or buildings. In recent years, a laminated glass having various functions imparted in addition to the safety such as the scattering prevention, has been used. In particular, demand for glass having lightweight and both rigidity and sound insulation satisfied, is high. Patent Document 1 has proposed a laminated glass having rigidity and sound insulation satisfied while being light in weight, by letting it have an intermediate film of which the shear storage modulus and loss factor are within specific ranges.

DISCLOSURE OF INVENTION

Technical Problem

However, the laminated glass excellent in rigidity as disclosed in Patent Document 1, has had such a problem that a plasticizer contained in the intermediate film tends to bleed out by the influence of heat, light and water, whereby edge foaming is likely to occur at the edge portion of the intermediate film.

The present invention has been made in view of the above problem, and an object thereof is to provide a laminated glass excellent in edge foaming resistance and rigidity.

Solution to Problem

The present inventors have conducted intensive studies in order to solve the above problem, and as a result, they have found that the intermediate film for a laminated glass excellent in rigidity has a problem that since a plasticizer contained in the intermediate film is likely to bleed out, it is difficult to maintain the plasticizer, and have arrived at the present invention.

That is, the present invention provides a laminated glass in which a pair of glass plates and an intermediate film containing a plasticizer, provided between the pair of glass plates, are laminated, characterized in that the shear storage modulus G′ of the intermediate film is from 2 to 100 MPa, and the outer peripheral edge of the intermediate film is present inside than the outer peripheral edges of the two glass plates constituting the pair of glass plates, at least at a part of the entire outer periphery of the laminated glass.

Advantageous Effects of Invention

According to the present invention, it is possible to provide a laminated glass excellent in edge foaming resistance and rigidity.
