- test substrate was immersed in a 3% aqueous solution of ammonium persulfate at room temperature for 3 minutes, washed with water, further immersed in a 10% aqueous solution of sulfuric acid at room temperature for 1 minute, and then washed with water. Then this The substrate is immersed in a 30 ° C catalyst solution (Meltex, 10 vol% aqueous solution of Metal Plate Activator 350 (trade name)) for 7 minutes, washed with water, and a 85 ° C nickel plating solution (Meltex product).
- the plate was immersed in a 20 vol% aqueous solution of Mel-plate Ni-865M (trade name), pH 4.6) for 20 minutes, subjected to nickel plating, immersed in a 10 vol% aqueous sulfuric acid solution at room temperature for 1 minute, and washed with water.
- the test substrate was immersed for 10 minutes in a gold plating solution of 95 ° C. (available from Meltex, 15 vol% of OLECT portless UP (trade name) and 3 vol% of potassium cyanide, pH 6), and electroless gold plating was performed. Thereafter, it was washed with water, further immersed in warm water of 60 ° C. for 3 minutes, washed with water, and dried. A cellophane adhesive tape was adhered to the obtained electroless gold plating evaluation substrate, and the state when peeled off was observed.
- the (flexibility) cured film is bent at 180 degrees and observed. The following criteria were used:
- a rosin-based plaque was applied to the cured film and immersed in a solder bath at 260 ° C. for 5 seconds. This was defined as one cycle and repeated three cycles. After being allowed to cool to room temperature, a peeling test was performed using cellotape (registered trademark), and evaluated according to the following criteria.
- the photosensitive resin composition of the present invention has no tackiness and high sensitivity, and its cured film has excellent flexibility, solder heat resistance, and chemical resistance. Also, it is excellent in gold plating resistance and the like, so that it is particularly suitable as a photosensitive resin composition for printed circuit boards.
- the photosensitive resin composition of the present invention is excellent in photosensitivity in forming a coating film by exposure and curing with ultraviolet light, and the obtained cured product has excellent flexibility, adhesion, pencil hardness, and the like. It also satisfies solvent resistance, acid resistance, heat resistance, gold plating resistance, etc., and can be suitably used for photocurable paints, photocurable adhesives, etc., and especially photosensitive resin compositions for printed circuit boards. Suitable for things!
