FIELD: security applications.
SUBSTANCE: invention can be used to obtain hidden images in security applications. A printing system for printing a security feature in the form of a latent image contains at least three compositions (RI), (C1) and (C2). In this case, (RI) is reactive ink containing a silane compound (A) containing at least the first and second polymerizable fragments that are different from each other and are capable of polymerization by different mechanisms. (C1) is the first catalyst composition containing a substance capable of reacting with the silane compound (A) of the composition (RI) and stimulating the polymerization of the first polymerizable fragment. (C2) is the second catalyst composition containing a substance capable of reacting, alone or in the presence of composition (C1), with the silane compound (A) of the composition (RI) and stimulating the polymerization of the second polymerizable fragment. A method for obtaining a printed object in the form of a security feature and a printed object obtained by the method are proposed.
EFFECT: invention ensures the formation of images used as a security feature in security applications for fast printing on porous and non-porous surfaces with good mechanical properties and adhesion.
