Abstract

Method and kit for providing visual effects on fibres, for example human keratin fibres. In the method, fibres are provided coated with a composition. The composition comprises monomer(s) and optionally a cosmetically acceptable carrier. The monomer(s) are capable of forming a polymer after exposure to electromagnetic radiation having a wavelength of from about 300 nm to about 750 nm. The monomer(s) are selected from the group consisting of acrylates monomers, methacrylate monomers, acrylamide monomers, methacrylamide monomers, styrene monomers, vinyl pyrrolidinone monomers, vinylpyrrolidone monomers, and mixtures thereof. The monomer(s) have a molecular weight in the range from about 100 g/mol to about 5000 g/mol. The monomer(s) have a functionality of between 1 and 100. The composition has a kinematic viscosity of from about 0.5 cSt to about 1500 cSt, measured at 23° C. In the method, a forming means is applied onto the fibres. The forming means orders the composition into a pattern and is permeable to UV radiation. In the method, the forming means is irradiated with electromagnetic radiation having a wavelength of from about 300 nm to about 750 nm and the the forming means is removed from the fibres.
