PROBLEM TO BE SOLVED: To obtain a high sensitivity planographic printing plate excellent in printing resistance and chemical resistance, free from the residue of ink of a ball-point pen and excellent also in fine dot reproducibility, pressure resistance and dispersion stability. SOLUTION: This photosensitive resin compsn. forms a photosensitive layer contg. a compd. generating an acid and/or a radical under light, active radiation or electron beams on a substrate. The photosensitive layer contains an acicular filler having an acicularity ratio of 2-5 or a platy filler having a plate ratio of 3-500 by 0.1-5.0 pts.wt. based on 100 pts.wt. solid components in the layer. The filler may be subjected to various surface treatments. The photosensitive layer further contains flat platy fine particles having uniaxial orienting property. |
