본 발명은 비할로겐 조성으로 환경 부하가 적음와 동시에 난연성 및 보존 안정성이 함께 우수하고, 가요성이 풍부한 경화 피막을 형성할 수 있는 난연성 광경화성 수지 조성물, 그의 드라이 필름 및 경화물, 및 이들에 의해 솔더 레지스트 등의 난연성 경화 피막이 형성되어 이루어지는 인쇄 배선판을 제공한다. The present invention is a flame-retardant photo-curable resin composition, a dry film and a cured product thereof, which are capable of forming a cured film having a low environmental load, excellent flame retardancy and storage stability, and a flexible, non-halogen composition. Provided is a printed wiring board on which a flame-retardant cured film such as a resist is formed. 난연성 광경화성 수지 조성물은 카르복실기 함유 수지와, 카르복실기 함유 수지 또는 그의 바니시에 5 중량％ 이상 가용인 가용성 포스파젠 화합물과, 광중합 개시제를 함유한다. 바람직하게는 상기 카르복실기 함유 수지는 카르복실기 함유 폴리우레탄 수지이다. 적합하게는 추가로 광중합성 단량체를 함유하고, 또는 추가로 열경화성 수지를 함유한다. 이러한 난연성 광경화성 수지 조성물, 특히 열경화성 수지를 함유하는 광경화성 열경화성 수지 조성물은 솔더 레지스트로서 바람직하게 사용할 수 있다. The flame-retardant photocurable resin composition contains a carboxyl group-containing resin, a soluble phosphazene compound soluble in 5% by weight or more of the carboxyl group-containing resin or its varnish, and a photopolymerization initiator. Preferably, the carboxyl group-containing resin is a carboxyl group-containing polyurethane resin. Suitably it further contains a photopolymerizable monomer, or further contains a thermosetting resin. Such a flame-retardant photocurable resin composition, especially the photocurable thermosetting resin composition containing a thermosetting resin, can be used suitably as a soldering resist. 난연성 광경화성 수지 조성물, 드라이 필름, 경화 피막, 솔더 레지스트 Flame retardant photocurable resin composition, dry film, cured film, solder resist

Polythiol sealant compositions

Provided are sealant compositions that include a first component and second component. The first component contains a polysulfide, a polythioether, or a copolymer or combination thereof containing pendant or terminal thiol groups, while the second component contains an ethylenically-unsaturated compound and either the first or second component further contains a photoinitiator. Alternatively, the second component can contain a polyepoxide and either the first or second component can contain a photolatent base and a photosensitizer. The first or second component further contains a colorant that substantially reflects or substantially transmits light over the wavelength range from 350 nm to 500 nm. These compositions can provide cure-on-demand sealant formulations that comply with Class B sealant regulations on color, provide an acceptable depth of cure, and allow two-part mixing to be easily distinguishable.

Propylene random copolymer for use in film applications

The present invention is directed to a polypropylene composition (P) comprising a bimodal copolymer of propylene and 1-hexene prepared in the presence of a metallocene catalyst, said bimodal copolymer having a melt flow rate MFR2 in the range of 4.0 to 20.0 g/10 min. Further, the present invention is directed to a method for preparing the copolymer (C) and an article comprising said polypropylene composition (P).
