Abstract
Composizione polimerica fotosensibile, particolarmente una fotoemulsione adatta a consentire l'incisione di disegni su quadri piani da stampa serigrafica mediante impiego di un fascio di raggi Laser, costituita da almeno una resina poliestere acrilata, da alcool polivinilico, da poliuretano acrilato, e da almeno una resina epossidica acrilata con almeno un composto fotoiniziatore a base di chetoni aromatici, tali da reagire a lunghezze d'onda della radiazione Laser utilizzata comprese fra 280 e 400 nanometri, e con una oligoammina acrilata, pigmenti, additivi disaeranti e distendenti e 2-metil-pirrolidone; detta resina epossidica acrilata e detto poliuretano acrilato sono impiegati al 75% in tripropilenglicole diacrilato, mentre detto alcool polivinilico รจ impiegato in soluzione acquosa al 15%.Photosensitive polymeric composition, particularly a photoemulsion suitable to allow the engraving of drawings on flat screens for silk-screen printing by using a laser beam beam, consisting of at least one acrylate polyester resin, polyvinyl alcohol, polyurethane acrylate, and at least one epoxy resin acrylate with at least one photoinitiator compound based on aromatic ketones, such as to react to wavelengths of the laser radiation used between 280 and 400 nanometers, and with an acrylate oligoamine, pigments, deaerating and relaxing additives and 2-methyl- pyrrolidone; said epoxy acrylate resin and said polyurethane acrylate are used 75% in tripropylene glycol diacrylate, while said polyvinyl alcohol is used in 15% aqueous solution.
