Definitions
- the hydrophilic coating or layer contains colloidal silica, generally in the ratio of binder solids to silica solids of 1:50 to 1:3 and preferably 1:20 to 1:10.
- the hydrophilic layer containing colloidal silica is applied to any hydrophobic surface and is preferably a polymeric support such as a polyolefin support which includes, for example, paper coated with polyethylene or polymerized olefin mixtures.
- the hydrophilic coating or layer is an aqueous dispersion such as a hydrophilic colloidal including gelatin and the like, Water-soluble polymers, etc.
- the improved method of this invention provides highly increased adhesion to the hydrophobic support or underlayer without the necessity of pretreatment thereof, such as by flame treatment, electron bombardment and chemical treatments.
- This process is especially useful in the production of photogr-aphic elements wherein a coating of the above silicacontaining layer and an overcoated silver halide layer can be carried out simultaneously on a hydrophobic support surface.

PUBLISHED APR-IL lat, 1970 T873,009 METHGD 0F COATING 0N HYDROPHOBIC MATERIALS Robert Benton Campbell, Kodak Park Division, Rochester, 'N.Y. 14650, and Charles Harold Galiin II, 222 Escuela St., Apt. 23, Mountain View, Calif. 94040 Filed Nov. 7, 1969, Ser. No. 874,982 Int. Cl. G03c 1/80, 1/86 TLS. Cl. 96-85 No Drawing. 6 Pages Specification An improved method is provided for adhering a hydrophilic layer to a hydrophobic su port or layer in the production of a multilayer or coated element. Accordingly, the hydrophilic coating or layer contains colloidal silica, generally in the ratio of binder solids to silica solids of 1:50 to 1:3 and preferably 1:20 to 1:10. The hydrophilic layer containing colloidal silica is applied to any hydrophobic surface and is preferably a polymeric support such as a polyolefin support which includes, for example, paper coated with polyethylene or polymerized olefin mixtures. Preferably, the hydrophilic coating or layer is an aqueous dispersion such as a hydrophilic colloidal including gelatin and the like, Water-soluble polymers, etc. The improved method of this invention provides highly increased adhesion to the hydrophobic support or underlayer without the necessity of pretreatment thereof, such as by flame treatment, electron bombardment and chemical treatments. This process is especially useful in the production of photogr-aphic elements wherein a coating of the above silicacontaining layer and an overcoated silver halide layer can be carried out simultaneously on a hydrophobic support surface.
