A cohesive product that has one or more layers of a substrate and a synthetic water-based cohesive polymer that is applied to the substrate and defines an outer surface of the product. The synthetic water-based cohesive polymer is an inherently crystalline elastomer whose polycrystalline structure has been disrupted such that the elastomer possesses a cohesive property.

Cohesive products

A laminated tape/bandage comprising a layer of transversely-spaced, longitudinally-extending elastic strands between a pair of outer layers, at least one of which is a warp-knitted (weft insertion) fabric oriented with the knit yarns extending longitudinally and generally parallel to the orientation of the elastic strands.

Elastic bandage

A photoresist composition comprising a sensitizer in a binder that is a naphthol polymer alone or mixed with another compatible resin such as a novolak resin or a polyvinyl phenol. The use of the naphthol resin as a portion of the binder increases the heat distortion temperature of the photoresist composition.

Photoresist composition of cocondensed naphthol and phenol with

This invention relates to resin blends of naphthol resins and novolak resins. Naphthol resins are acid catalyzed condensation products of an aromatic alcohol with an aldehyde where the aromatic alcohol is a naphthol or a mixture of a naphthol and a phenol. The blends of the invention preferably contain a total of from 5 to 35 mole percent repeating units derived from naphthol. The blends are useful as molding compounds or as film forming materials.

Naphthol novolak resin blend

Novel resins are disclosed that are the reaction products of an aldehyde and an aromatic alcohol mixture of naphthol, preferably 1-naphthol, and a phenol. The molar ratio of the naphthol to the phenol in the reaction mixture can vary from about 20 to 1 to 1 to 20. The resins are formed by condensing the aldehyde with the aromatic alcohol mixture in the presence of an acid catalyst where the molar ratio of the aromatic alcohol to aldehyde is less than 1. The resins of the invention are characterized by melt temperature higher than the melt temperatures of conventional novolak resins.
