Problems solved by technology

However, attempts to create a planarized film for color filters have resulted in problems such as a significant decrease in planarization and transparency.
In addition, although polyimide and polyamic acid are soluble in solvents such as N-methyl-2-pyrrolidone and γ-butyrolactone, they have low solubility in diol-based solvents and ester-based solvents, making it difficult to apply to flat surfaces. Chemical film production line

Synthetic example 1

[0211] HBPDA 12.0 g, HBPA 10.2 g, THPA 0.95 g, and BTEAC 0.22 g were reacted in PGMEA 54.48 g at 120° C. for 19 hours to obtain a polyester polymer solution (solid content concentration: 30.0% by mass (P1). The resulting The Mn of the polyester polymer is 2,280, and the Mw is 4,200.

Synthetic example 2

[0213] After dissolving 14.6 g of DA-4P in 40.68 g of DMAc, it was cooled with water and kept at 23°C. 4.90 g of CBDA and 7.60 g of THPA were reacted in this solution at 23 degreeC for 24 hours, and the amino group containing carboxylic acid compound solution (40.0 mass % of solid content concentration) was obtained.

Abstract

A multi-core processor system includes a given configured to queue an interrupt process of a software interrupt request to the given core, and execute queued processes in the order of queuing at the given core; execute preferentially an interrupt process of a hardware interrupt request to the given core over a process under execution at the given core; determine whether the software interrupt request is a specific software interrupt request; and perform control to preferentially execute the interrupt process without queuing, upon determining that the software interrupt request is the specific software interrupt request.

Description

technical field [0001] The present invention relates to a thermosetting film-forming polyester composition and a cured film obtained from the thermosetting film-forming polyester composition. More specifically, the present invention relates to a polyester composition for forming a thermosetting film and a cured film thereof having high transparency, flattening property, liquid crystal orientation capability, high solvent resistance, and heat resistance, and to the cured Membrane application. This polyester composition for thermosetting film formation is suitable especially as a color filter overcoat agent which has a liquid-crystal orientation function in a liquid crystal display. Background technique [0002] In general, optical devices such as liquid crystal display elements, organic EL (electroluminescent) elements, and solid-state imaging elements are provided with a protective film to prevent the element surface from being exposed to solvents and / or heat during the man...
