FIELD: chemistry.
SUBSTANCE: ink contains photopolymerisable monomers, which contain compound of group of compounds (A), which do not produce sensitising impact on skin, and compound of group of compounds (B), which do not produce sensitising impact on skin. Group of compounds (A) consists of caprolactone-modified dipentaerithritehexaacrylate, polyethoxylated tetramethylolmethanetetraacrylate, modified with ethylene oxide bisphenol A diacrylate, caprolactone-modified neopentylglycoldiacrylate of hydroxytrimethylacetic acid, polypropyleneglycoldiacrylate [CH2=CH-CO-(OC3H6)n-OCOCH=CH2 (n≈12)], hydroxyethylacrylamide, trimethylolpropanetrimethacrylate and tricyclodecanedimethanoldimethacrylate. Group of compounds (B) consists of modified with ethylene oxide phanolacrylate, isostearylacrylate, modified with ethylene oxide trimethylolpropanetrimethacrylate, stearylmethacrylate and glyceroldimethacrylate. Viscosity of claimed ink constitutes from 5 to 18 mPa•s at 25°C or from 2 to 20 mPa•s at 60°C. Ink cartridge and inkjet recording device, including said ink are also claimed.
EFFECT: dye possesses safety with respect to skin sensitisation, low viscosity, improved properties when hardened and provides safe printing material.
