PHOTOPOLYMERISING COMPOSITION FOR PRINTING ON TEXTILE MATERIALS Russian patent published in 2011 - IPC D06P5/20 G03F7/28 G03F7/33 

FIELD: textile, paper.

SUBSTANCE: composition includes a (meth)acrylic oligomer, a photopolymerising (meth)acrylic monomer with more than one (meth)acrylic group, a photoinitiator, a non-ionogenic surfactant and a dying agent - a product of dye application - cation, direct, acid, active or disperse one at nanostructured particles of montmorillonite or montmorillonite modified with cationic surfactant, or a hydrotalcite. To reduce time of irradiation with UV light required for fixation, and to increase stability of dying, the composition may additionally include a coinitiator and a (meth)acrylic polymer, and also a defoaming agent to prevent foaming, when composition components are mixed. To improve dispersion of dyed nanostructured particles, the composition contains a non-ionogenic surfactant.

EFFECT: increased stability of dyed material to physical-chemical effects, reduced time of irradiation with UV light required for strong fixation of dying, and provision of additional colouristic effects by variation of both dye content on particles and content of dyed particles.
