    摘要: In the manufacture of prepreg using various types of resin varnish having different properties, prepreg having good appearance and desired properties is manufactured without decreasing productivity. A prepreg manufacturing apparatus is able to perform, in a base material feeding path, immersing a base material in resin varnish in a tray, scraping off the excess resin varnish on the base material with scraping rollers which are provided above the tray, and thereafter drying the base material with a drying device. The prepreg manufacturing apparatus is configured such that, on the base material feeding path, the distance from the liquid surface of the resin varnish in the tray to the scraping rollers and the distance from the scraping rollers to the drying device are adjustable.

    摘要: It is an object of the present invention to provide a resin composition which can realize a printed wired board having not only low water-absorbing property but also excellent heat resistance after moisture absorption, flame retardancy, and solvent solubility. It is another object of the present invention to provide a prepreg and a monolayer or laminate which use the resin composition, and a metal foil clad laminate and a printed wired board which use the prepreg. A resin composition of the present invention contains one or two or more cyanate ester compounds (A) represented by the following formula (1) and an epoxy resin (B): wherein R1, R2, R3, and R4 represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, and may be the same or different from each other; and n represents an integer of 1 to 50.
