  • Publication number: 20120305862
    Abstract: This invention provides a water-based primer composition comprising (A) an aqueous dispersion of modified polyolefin, (B) an aqueous urethane resin and/or aqueous acrylic resin, (C) a pyrazole-blocked polyisocyanate compound and (D) an electrically conducting pigment, its (C) pyrazole-blocked polyisocyanate compound content being within a range of 5-50 mass % based on the total solid content of the components (A), (B) and (C), said electrically conducting pigment (D) containing an electrically conducting metal oxide (D-1), and the content of the electrically conducting pigment (D) being within a range of 50-200 mass parts per 100 mass parts of the total solid resin content in the composition; and also methods for coating plastic shaped articles using the composition.

  • Patent number: 7077941
    Abstract: A multi-layer electrodeposition coating film-forming method which comprises subjecting a cationic electrodeposition coating composition containing at least two emulsions to an electrodeposition coating, said cationic electrodeposition coating composition being such that a difference in an electrical quantity (a) required for deposition starting between a first coating composition comprising a first emulsion and a second coating composition comprising a second emulsion in two emulsions selected from the at least two emulsions is in the range of 50 to 400 C/m2.

  • Patent number: 6662115
    Abstract: A method for comparing DNA base sequences by comparing similarities between two amino acid sequences translated from two DNA base sequences, respectively, includes (1) a step of dividing each of the first DNA base sequence and the second DNA base sequence into groups of successive three nucleotides each, translating each of these groups of nucleotides into an amino acid, and thereby obtaining a first amino acid sequence and a second amino acid sequence, and (2) a step of determining similarities between each amino acid of the first translated amino acid sequence and each amino acid of the second translated amino acid sequence in view of nucleotide insertions or deletions in the first and second DNA base sequence and amino acid insertions or deletions in the first and second translated amino acid sequence. The method is repeated by shifting the base sequences one base at a time.

  • Publication number: 20030102217
    Abstract: The present invention provides a method for forming a multilayer coating film, comprising: applying a colored cationic electrodeposition coating composition (A) to a metal substrate by electrodeposition; applying a bright pigment-containing clear coating composition (B) to the electrodeposition coating, which is either uncured or thermally cured; and then curing the uncured electrodeposition coating and the clear coating, or the clear coating.
