Waterborne photoresists having non-ionic fluorocarbon surfactants. |
摘要 |
Waterborne photoimageable compsn. comprises: (a) 30-80 wt.% of a latex binder polymer including carboxylic acid cpds. giving an acid number of 50-250; (b) 15-50 wt.% of a fraction of alpha, beta-ethylenically unsatd. monomers; (c) 0.1-25 wt.% photoinitiator; (d) 1-40 wt.% of a neutralising base and/or polyether polyurethane associate thickener in amt. to stabilise emulsion of binder; and (e) 0.5-3.0 wt.% of a surfactant of a fluoroaliphatic oxyethylene adduct of formula (I). CF3-(CF2)n-Y-Xm-Z (I); n=0-20; Y = SO2-N (1-10C) alkyl; X = CH2-CH2-O or CH(CH3)-CH2-O; m=0-20; and Z= CH2-CH2-OH or CH(CH3)-CH2OH. Also claimed is a support sheet and layer of the compsn. above forming a dry film. |
