Writing material getting no spill, record protected (9)
I believe the answer is:
Here is my best explanation:
'writing material' is the definition.
(I've seen this before)
'record protected' is the subsidiary indication.
'record' becomes 'note' (note is a kind of record).
'protected' becomes 'paper' (I can't explain this - if you can you should believe this answer much more).
'getting no spill' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
(Other definitions for notepaper that I've seen before include "Stationery item", "What correspondent needs", "Bond", "perhaps, a contributor to writer's block", "Correspondence on this", "used to correspond", "Whereon Handel may have written", "Sheets for writing", "Letters are sent on it" and "Material for letters".)
