A plurality of component layers of thick film forming materials are formed simultaneously on a glass substrate by simultaneously applying a plurality of thick film forming pastes to the glass substrates, or by simultaneously transferring the plurality of component layers of thick laminated film formed on a transfer base sheet from the transfer base sheet to the glass substrate. At least one of the plurality of component layers formed on the glass substrate is patterned, and then the plurality of component layers are burned simultaneously to form a patterned thick laminated film on the glass substrate.

A liquid toner and an ink composition, which comprise a dispersion of copolymer resin particles composed of at least two different monomer components in a dispersion medium. The copolymer resin particles and the dispersion medium are related to each other such that the difference .DELTA..delta..sup.1 between the solubility parameter value .delta.p.sup.1 of a homopolymer composed only of at least one monomer component in the copolymer resin and the solubility parameter value .delta.s.sup.1 of the dispersion medium is not smaller than 1.0, and that the difference .DELTA..delta..sup.2 between the solubility parameter value .delta.p.sup.2 of a homopolymer composed only of at least one other monomer component and the solubility parameter value .delta.s.sup.1 of the dispersion medium is not larger than 1.0, and further that the difference .DELTA. between .DELTA..delta..sup.1 and .DELTA..delta..sup.2 (.DELTA..delta..sup.1 -.DELTA..delta..sup.2) is at least 0.5. Moreover, each copolymer resin particle comprises a nuclear portion which is insoluble in the dispersion medium, and an outer skin portion which wraps the nuclear portion, and which is soluble or swellable in the dispersion medium. The liquid toner is a dispersion of the copolymer resin particles in an electrically insulating dispersion medium. The liquid toner is free from sedimentation, aggregation or other problem even if the pigment content is increased, and hence excellent in dispersibility and free from gelation. The ink composition is a dispersion of the copolymer resin particles in a dispersion medium. Even if the pigment or other particle content is increased, sedimentation, aggregation or other problem will not occur. Thus, the ink composition exhibits excellent dispersibility and is free from gelation and superior in coatability.
