Some embodiments provided herein relate to a thermoplastic material that can include a thermoplastic surface, a protective coating, and a degradable intermediate layer.

A laminate includes the following substantially coextensive layers in the following order: (a) a non-sealable, self-supporting, thermoformable copolyester film layer having a first surface and a second surface, the second surface constituting an outermost, exposed surface of the laminate; (b) a laminating adhesive layer on the first surface of the thermoformable copolyester film layer; and (c) a self-supporting, thermoformable structural film layer having a first surface and a second surface, the first surface contacting the laminating adhesive layer.

The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

In a pneumatic tire containing as an inner liner material a laminate of a film of a thermoplastic resin or a thermoplastic elastomer composition and a layer of a rubber composition for improving the adhesive strength between the film and the rubber composition, the rubber composition comprises 100 parts by weight of a rubber component, 0.5 to 20 parts by weight of a condensate between a compound expressed by formula (1): ##STR00001##
wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are hydrogen, a hydroxyl group or a C1 to C8 alkyl group, and formaldehyde, 0.25 to 200 parts by weight of a methylene donor, and a vulcanizing agent; and a weight ratio of the methylene donor content to the condensate content is 0.5 to 10.
