A pretreatment formulation comprising at least one ink fixation agent and at least one vinyl acetate/ethylene copolymer (VAE) and/or a VAE derivative, the formulation being free of a pigment or a dye, wherein VAE is a copolymerization product of vinyl acetate and ethylene, having vinyl acetate content between 60 and 95%, and ethylene content between 5 and 40% (w/w) and wherein the VAE derivative is a modified VAE wherein
- a further monomer is introduced along the VAE chain;
- or
- at least a portion or all of the vinyl acetate monomers and/or at least a portion or all of the ethylene monomers are chemically functionalized;
- or
- at least a portion or all of the vinyl acetate monomers are chemically functionalized, and none of the ethylene monomers are chemically functionalized;
- or
- none of the vinyl acetate monomers are chemically functionalized, and a plurality or all of the ethylene monomers are chemically functionalized;
- or wherein
- the backbone of a VAE polymer is chemically functionalized.
A fabric coated with a dry film of a pretreatment formulation comprising VAE and/or a VAE derivative, and at least one ink fixation agent, wherein said dry film is overlayed with an ink film or an ink pattern.
