PROBLEM TO BE SOLVED: To provide an ideal ink-jet recording method which can perform printing at a full color, at a low cost, is good in printing quality, and excellent in concentration, gloss, and image reliability and can provide a printed matter with quality feeling near that of a commercial printed matter excellent in smearness (smear resistance) by combining ink-jet
Background In this review, we examine the continually expanding and increasingly compelling data linking radiation and various chemicals in our environment to the current high incidence of breast cancer. Abstract Singly and in combination, these toxicants may have contributed significantly to the increasing rates of breast cancer observed over the past

- What is phenylenediamine used for?
- A hair dye component, paraphenylenediamine, as a contact allergen for treatment of inflammatory diseases. ChEBI: A phenylenediamine in which the amino functions are at positions 1 and 4 of the benzene nucleus. A white to purple crystalline solid (melting point 234 F) that turns purple to black in air.
- Is phenylenediamine photolytic?
- Photolytic. A carbon dioxide yield of 53.7% was achieved when phenylenediamine (presumably an isomeric mixture) adsorbed on silica gel was irradiated with light (λ >290 nm) for 17 h (Freitag et al., 1985).
- Can p-phenylenediamine be used in hair dye?
- P-phenylenediamine, as a chemical dye, is currently permitted for use in hair dye production, but there is a clear usage limits. According to China "Hygienic Standard for Cosmetics," the content of p-phenylenediamine in hair dyes should not exceed 6%.
- What color is p-phenylenediamine?
- Paraphenylenediamine (PPD) is a colorless compound oxidized by hydrogen peroxide in the presence of ammonia. It is then polymerized by a coupling agent to produce a color. p-Phenylenediamines are white to slightly red crystalline solids. They have been described as gray “light brown” which may result from exposure to air.
- Is phenylenediamine carcinogenic?
- There is still no literatures regarding to whether phenylenediamine is carcinogenic or not; but there is literature basis regarding to that p-phenylenediamine drug is toxic organic. We can refer to Shanghai Science and technology press (November 1985) "reagent Handbook" (second edition), page 980.
- Is p-phenylenediamine flammable?
- Non flammable p-Phenylenediamine causes allergic reactions with skin. It is widely used in hair dyes. It eventually forms Bandrowski′s base, which is found to be the primary cause for allergy. p-Phenylenediamine exposure results in dermatitis, urticaria and anaphylaxis.
