  • Patent number: 11945962
    Abstract: The present invention provides a cationic electrodeposition coating composition that has both good anti-cissing property and good coating film appearance. This is a cationic electrodeposition coating composition containing a silicone compound (A) having an SP value of more than 10.5 and 15.0 or less, and a film forming resin (B), wherein the silicone compound (A) is contained in an amount of 0.01 parts by mass or more and 4.5 parts by mass or less per 100 parts by mass of the resin solid content of the film forming resin (B). For example, the silicone compound (A) is at least one species selected from the group consisting of a polyether modified silicone compound (A-1), a polyester modified silicone compound (A-2), and a polyacrylic modified silicone compound (A-3).

  • Patent number: 7854960
    Abstract: In one embodiment of the present invention, an optical device is manufactured by printing a pixel, wherein said method includes deciding plural discharging positions inside each pixel of the optical device, arranging these plural discharging positions on different positions in lateral direction of the pixel respectively, specifying each of the plural nozzles by a natural number n counted sequentially from the end of the ink jet head, defining a surplus as b when dividing the natural number n with the repetitive number a (b is an integer satisfying: 0?b?a?1), corresponding the surplus b to each of the plural nozzles, repeating a unit step of discharging an ink from nozzles corresponding to the surplus b, finding “discharge coefficient” by measuring unevenness of ink discharging and changing the number of times of ink discharging.
