Information carrier precursor and information carrier produced therewith

A method for producing an information carrier precursor comprising a rigid sheet or support;

• a receiving layer configuration comprising at least one layer;
• and at least one substance, optionally provided pattern-wise, capable of and available for interacting in situ with at least one species diffusing through the receiving layer configuration to produce a functional species, wherein at least one layer of said receiving layer configuration is opaque, porous, has the capability of being rendered substantially transparent by penetration by a lacquer provided at the outermost surface of said receiving layer configuration and comprises at least one pigment and at least one binder, said method comprising the steps of:
• optionally applying at least one layer to a rigid sheet or support thereby providing an outermost surface;
• and applying as a continuous or discontinuous layer or print in at least one application step a receiving layer configuration to a rigid sheet or support or the outermost surface of said optionally applied at least one layer, at least one substance capable of and available for interacting in situ with at least one species diffusing through the receiving layer configuration to produce a functional species being provided in at least one of the constituent receiving layers and the at least one optionally applied layer and rigid sheet or support in diffusion contact with the receiving layer configuration.

A method for producing an information carrier, said method comprising the following steps:

• (i) providing an information carrier precursor comprising a rigid sheet or support;
• a receiving layer configuration comprising at least one layer;
• and at least one substance, optionally provided pattern-wise, capable of and available for interacting in situ with at least one species diffusing through the receiving layer configuration to produce a functional species, wherein at least one layer of said receiving layer configuration is opaque, porous, has the capability of being rendered substantially transparent by penetration by a lacquer provided at the outermost surface of said receiving layer configuration and comprises at least one pigment and at least one binder;
• (ii) applying a composition comprising at least one functional species or functional species precursor pattern-wise to the outermost surface of said receiving layer configuration to produce a pattern in said information carrier precursor;
• (iii) applying the transparentizing lacquer to at least part of the areas of the outermost surface of the receiving layer configuration corresponding to the porous parts of the at least one opaque, porous layer thereby transparentizing at least in part the parts of the at least one opaque, porous layer which are opaque and porous to which the transparentizing lacquer has been applied;
• (iv) optionally curing said transparentizing lacquer;
• (v) if there are parts of the layer which are opaque and porous after step (iv) applying non-transparentizing lacquer to said opaque and porous parts of said outermost layer of said receiving layer configuration thereby filling the pores of those parts of said receiving layer configuration to which said transparentizing lacquer had not been applied;
• and
• (vi) optionally curing said non-transparentizing lacquer.

An information carrier obtained according to the method comprising the following steps:

• (i) providing an information carrier precursor comprising a rigid sheet or support;
• a receiving layer configuration comprising at least one layer;
• and at least one substance, optionally provided pattern-wise, capable of and available for interacting in situ with at least one species diffusing through the receiving layer configuration to produce a functional species, wherein at least one layer of said receiving layer configuration is opaque, porous, has the capability of being rendered substantially transparent by penetration by a lacquer provided at the outermost surface of said receiving layer configuration and comprises at least one pigment and at least one binder;
• (ii) applying a composition comprising at least one functional species or functional species precursor pattern-wise to the outermost surface of said receiving layer configuration to produce a pattern in said information carrier precursor;
• (iii) applying the transparentizing lacquer to at least part of the areas of the outermost surface of the receiving layer configuration corresponding to the porous parts of the at least one opaque, porous layer thereby transparentizing at least in part the parts of the at least one opaque, porous layer which are opaque and porous to which the transparentizing lacquer has been applied;
• (iv) optionally curing said transparentizing lacquer;
• (v) if there are parts of the layer which are opaque and porous after step (iv) applying non-transparentizing lacquer to said opaque and porous parts of said outermost layer of said receiving layer configuration thereby filling the pores of those parts of said receiving layer configuration to which said transparentizing lacquer had not been applied;
• and
• (vi) optionally curing said non-transparentizing lacquer.
