  • Patent number: 9969901
    Abstract: Provided is an aqueous resin composition in which a vinyl ester resin and a urethane resin having an aromatic ring are dispersed in an aqueous medium, in which the vinyl ester resin is obtained by allowing at least one epoxy resin selected from the group consisting of a novolak type epoxy resin and a bisphenol type epoxy resin to react with a compound having an acid group and a polymerizable unsaturated group, and the urethane resin is obtained by allowing polyol containing polyol having an aromatic ring and polyol having a hydrophilic group to react with a polyisocyanate. A primer using the aqueous resin composition is able to considerably improve adhesiveness between a substrate and a cured coating film of an active energy ray curable composition, even when the substrate is a sparingly adhesive substrate.

  • Patent number: 7760933
    Abstract: A parameter estimation method for estimating a parameter by estimating maximum a posteriori probability for input data. Operation for the input data is expressed by an inner product for the input data and the inner product is replaced by a Kernel function. By using the calculation result of the kernel function, a parameter is estimated. The method includes a step (offline operation) for learning a correlation between a plurality of learning input data in which a parameter to be estimated is known and the parameter corresponding to each of the learning input data; and a step (online operation) for estimating the parameter for the estimating input data in which a parameter to be estimated is unknown, by using the learned correlation.
