    摘要： A mixture of yellowish green-to-yellow emitting, gold- and aluminum-activated zinc sulfide and blue-emitting silveractivated zinc sulfide, in which the weight ratio of the latter to the former is within a range of 0.7 to 1.30, is valuable as a white-emitting phosphor for black and white television. When at least one red-emitting phosphor selected from europium-activated yttrium oxysulfide, europium-activated yttrium oxide and europium-activated yttrium vanadate is incorporated into the above white-emitting phosphor, the resulting composite can cover a more wide white region for black and white television.

    摘要： When a metal surface treating agent consisting of a zinc phosphate comprising given amounts of water-soluble aluminum, arsenic and fluorine compounds added thereto is employed as pretreatment before electrophoretic painting, the dissolving quantity of the phosphating coating is reduced, and it results in formation of a uniform electrodeposition-coated film which has excellent corrosion resistance and is free from rough surface; moreover, as the paint is not contaminated, the paint can be stable for a long time. Finish of the electrodeposition coating can be also improved by using pretreatment prepared by adding further a small amount of Te and/or Bi.
