Abstract
There is disclosed a method of manufacturing a multi-layered article including a finished outer surface optionally having particular surface properties. The article can be a self-supported strip having a smooth outer surface. The method is, for example, suitable for the preparation of multi-layered articles such as a flexible intermediate transfer member (ITM) for use in an indirect printing system. Uses of such articles are also disclosed.
Claims20
A self-supported strip, comprising a fully cured surface coating and a base, wherein said fully cured surface coating in said self-supported strip is a release layer having an outer release surface, the release layer having an average roughness (Ra) of at most 250 nm on the outer release surface;
- and having a surface energy E1 on the outer release surface that is greater than a surface energy E0 on an opposite side of the release layer facing the base;
- wherein any defects present in the release layer have a decreasing defect density from a side of the release layer which faces the base to an opposite side of the release layer forming the outer release surface.
A self-supported strip, comprising a fully cured surface coating and a base, wherein said fully cured surface coating in said self-supported strip is a release layer having an outer release surface, the release layer having an average roughness (Ra) of at most 250 nm on the outer release surface;
- and having a surface energy E1 on the outer release surface that is greater than a surface energy E0 on an opposite side of the release layer facing the base;
- the self-supported strip further including a peelable flexible foil carrier having a carrier contact surface contacting the outer release surface;
- and wherein any defects present in the release layer have a decreasing defect density from a side of the release layer which faces the base to an opposite side of the release layer forming the outer release surface.
A self-supported strip, comprising a fully cured surface coating and a base, wherein said fully cured surface coating in said self-supported strip is a release layer having an outer release surface, the release layer having an average roughness (Ra) of at most 250 nm on the outer release surface;
- and having a surface energy E1 on the outer release surface that is greater than a surface energy E0 on an opposite side of the release layer facing the base;
- wherein said outer release surface is substantially free of defects, wherein said substantially free of defects is quantified by less than 0.01% of said outer release surface being covered by said defects;
- and wherein any defects present in the release layer have a decreasing defect density from a side of the release layer which faces the base to an opposite side of the release layer forming the outer release surface.
