3· Elektriskt isolerande papper enligt patentkravet 1, k ä n -netecknat därav, att papprets blida sidor är ytbelagda.
4· Elektriskt isolerande papper enligt patentkravet 1, k ä n -netecknat därav, att nämnda ytbeläggningsämne inte inne-häller mer än 200 ppm alkalimetaller.
5· Elektriskt isolerande papper enligt patentkravet 1, k ä n -netecknat därav, att nämnda ytbeläggningsämne inte inne-häller mer än 20 ppn alkalimetaller.
6. Elektriskt isolerande papper enligt patentkravet 1, k ä n -netecknat därav, att nämnda ytbeläggningsämne är närvarande i en mängd av 3-10 % av den totala vikten av det ytbelagda pappret.
7. Elektriskt isolerande papper enligt patentkravet 1, k ä n -netecknat därav, att det nämnda ytbeläggningsämnet är metyl-cellulosa. β. Elektriskt isolerande papper enligt patentkravet 7, k ä n -netecknat därav, att en 2 %:ig vattenlösning av nämnda metyl-cellulosa vid 20°C har en viskositet av ungefär 10-25 centipoise, och en substitutionsgrad av 1,64-1,92.
9. Elektriskt isolerande papper enligt patentkravet 1, kännetecknat därav, att det nämnda ytbeläggningsämnet är stärkelse.
10. Elektriskt isolerande papper enligt patentkravet 9, k ä n -netecknat därav, att en 10 %:ig vattenlösning av nämnda stärkelse vid 20°C har en viskositet som är mindre än ungeför 200 centipoise.
