Abstract
A method of simultaneously applying a plurality of liquid coating compositions to a moving web by the method of multi-layer coating; wherein the lowermost layer is comprised of water, with the wet coverage of water on the web being 2 cm.sup.3 or less per square meter (m.sup.2) of the web, and the layer immediately above the lowermost layer comprising a water-soluble coating solution having a viscosity greater than water and which is greater in thickness than the lowermost layer.
Claims9
A method of multi-layer coating in which at least two coating liquids are applied to a moving web, comprising:
- applying the coating liquid forming the lowermost layer is composed of water, with the wet coverage of water
- on said web being 2 cm.sup.3 or less per square meter (m.sup.2) of said web;
- and
- applying the layer immediately above said lowermost layer comprising a water soluble coating solution having a viscosity greater than water and which is greater in thickness than said lowermost layer.
A method of multi-layer coating in which at least two coating liquids are applied to a moving web, comprising the steps of:
- (a) apply a first coating liquid being composed of distilled water to form the lowermost layer, with the wet coverage of water on said web being 2 cm.sup.3 or less per square meter of said web;
- and
- (b) applying a second coating liquid immediately above said lowermost layer to form a second layer, said second coating liquid comprising a water soluble coating solution having a viscosity greater than water, said second layer being greater in thickness than said lowermost layer.
