Abstract: A trained model generation method relating to coating material. A trained model generation method for generating a trained model that determines, using a computer, evaluation of an article including coating material on a substrate, including: an acquisition step (S12) of causing the computer to acquire training data information including coating material information and the evaluation of the article, the coating material information corresponding to information of the coating material; a training step (S15) of training the computer based on a plurality of the training data from the acquisition step; and a generation step (S16) of causing the computer to generate the trained model based on training results in the training step. The trained model is configured to receive input information and to yield the evaluation, the input information corresponding to unknown information different from the training data. The input information corresponds to information including at least the coating material information.

Abstract: Provided is a fluorinated polymer that can impart excellent washing durability and water- and oil-repellency to fibers, said fluorinated polymer having a repeating unit derived from a fluorinated monomer (a) that comprises a first fluorinated monomer (a1) represented by the formula: CH2═C(—X1)—C(═O)—Y1—Z1—Rf1 [wherein X1 represents a halogen atom; Y1 represents —O— or —NH—; Z1 represents a direct bond or a bivalent organic group; and Rf1 represents a fluoroalkyl group having 1 to 20 carbon atoms] and a second fluorinated monomer (a2) represented by the formula: CH2═C(—X2)—C(═O)—Y2—Z2—Rf2 [wherein X2 represents a monovalent organic group or a hydrogen atom; Y2 represents —O— or —NH—; Z2 represents a direct bond or a bivalent organic group; and Rf2 represents a fluoroalkyl group having 1 to 20 carbon atoms].
