Abstract: A coating material of the present invention is a coating material containing: a fluorine-containing polymer having at least one of an iodine atom and a bromine atom; and a solvent, wherein a storage elastic modulus G′ of the fluorine-containing polymer is less than 360 kPa, and a total light transmittance of a mixed liquid obtained by mixing and stirring the fluorine-containing polymer and the solvent contained in the coating material is 1.0% or more, the mixed liquid being left to stand for 3 days, stirred again, and left to stand for 30 minutes to measure the total light transmittance.

Abstract: A fluorinated polymer suitable for deposition is provided. A film containing such a fluorinated polymer as a material is provided. A method for producing a film, by which such a film can readily be produced, is provided. Further, an organic photoelectronic element having such a film in its structure is provided.
A fluorinated polymer which satisfies the following requirements (1) to (3): (1) the melting point is 200° C. or higher, (2) the thermogravimetric loss rate when the temperature is increased at a temperature-increasing rate of 2° C./min under a pressure of 1×10−3 Pa, substantially reaches 100% at 400° C. or lower, (3) when the temperature is increased at a temperature-increasing rate of 2° C./min under a pressure of 1×10−3 Pa, the temperature width from a temperature at which the thermogravimetric loss rate is 10% to a temperature at which it is 90%, is within 100° C.

Abstract: A fluorinated polymer suitable for deposition and capable of favorable metal patterning, is provided. A resin film containing such a fluorinated polymer as a material is provided. Further, a photoelectronic element having such a resin film in its structure is provided.
A fluorinated polymer which satisfies the following requirements (1) to (3): (1) the melting point is less than 200° C., or no melting point is observed, (2) the thermogravimetric loss rate when the temperature is increased at a temperature-increasing rate of 2° C./min under a pressure of 1×10−3 Pa, substantially reaches 100% at 400° C. or lower, (3) when the temperature is increased at a temperature-increasing rate of 2° C./min under a pressure of 1×10−3 Pa, the temperature width from a temperature at which the thermogravimetric loss rate is 10% to a temperature at which it is 90%, is within 200° C.
